Stephen M. Delsanto (defendant) was indicted on one count of first degree sexual offense, in violation of N.C. Gen. Stat. § 14-27.4 (2003), and one count of taking indecent liberties with a child, in violation of N.C. Gen. Stat. § 14-202.1 (2003).
The State’s evidence at trial tended to show that defendant stayed at the home of his daughter (Bonnie) from 30 September 2002 to 3 *44October 2002. Defendant’s ex-wife (Brenda), son-in-law (Bobby), and twin grandchildren (H.B. and W.B.) were also living in the home. H.B. and W.B. were three years old at the time.
Bobby testified that on the evening of 3 October 2002, he was watching television with H.B. and W.B., when H.B. began rubbing her genital area. H.B. complained of pain and said “Pawpaw [defendant] touched me down there.” H.B. also said “Pawpaw messed with [W.B.’s] penis.” Bobby reported this information to Brenda, but did not tell Bonnie because Bonnie was sleeping at the time.
The following day, Brenda told Bonnie what Bobby had learned. Bonnie asked H.B. and W.B. whether they spoke with Bobby the night before. H.B. said yes, and that defendant had touched her “ginny,” her shortened term for vagina. Bonnie retrieved a doll and asked H.B. to show Bonnie where defendant had touched H.B. H.B. spread the doll’s legs and put her finger on the genital area. Bonnie called the Davie County Department of Social Services and Detective John Stephens (Detective Stephens) with the Davie County Sheriff’s Department.
Detective Stephens interviewed H.B. He testified that H.B. told him that her “Pawpaw touched her gina and put his finger in there, and it hurt.” H.B. also stated that defendant touched W.B.’s genitals. Detective Stephens was unable to successfully interview W.B. Detective Stephens made an appointment for H.B. to visit a pediatrician, Dr. Kathleen Russo (Dr. Russo), for an evaluation. Detective Stephens did not make an appointment for W.B. because, based on the allegations, there would have been no physical evidence of abuse.
Dr. Russo testified that she had received advanced recognition by the University of North Carolina Child Medical Evaluation Program, which signified that she had received advanced training in child sexual abuse. Dr. Russo testified that she examined H.B. on 18 October 2002. Dr. Russo asked H.B. if anyone had “touched [her] or hurt [her] some place that [she] did not like.” H.B. responded that defendant touched her “inside” her genitals. H.B. also demonstrated this act on an anatomically correct doll.
Dr. Russo then completed a physical examination but did not note any trauma or indications of abuse in H.B.’s genital area. Dr. Russo testified that although she did not observe any physical manifestations of sexual abuse, the examination was “absolutely consist*45ent” with H.B.’s assertion that defendant touched her genital area. Dr. Russo explained that the anatomy of the female genital area is such that healing and return to the pre-trauma condition can occur very rapidly. Dr. Russo then testified that she diagnosed H.B. as having “suffered from the sexual abuse that she disclosed to [Dr. Russo] and [H.B.’s] family.”
L.B., defendant’s twenty-seven-year-old niece, also testified at trial that defendant was her babysitter when she was about four years old. L.B. testified that defendant would tell her to lie on the bed, then he would remove her pants and underwear, touch her genital area and perform oral sex on her. She also stated that on one occasion defendant made her touch and kiss his penis. L.B. testified that she only told her parents and stepmother about this abuse, but that she was aware that other family members had discussed the abuse with Bonnie.
Deborah Gordon (Gordon) testified on behalf of defendant. On cross-examination, Gordon testified that she helped retrieve some of defendant’s belongings from Bonnie’s home. Gordon testified that defendant had a backpack of “vulgar” magazines and some pairs of women’s underwear.
The jury convicted defendant of first degree sexual offense with H.B., but acquitted defendant on the charge of indecent liberties with W.B. The trial court entered judgment on 15 September 2003 and sentenced defendant to a minimum term of 288 months and a maximum term of 355 months in prison. Defendant appeals.
I.
Defendant assigns error to the trial court’s admission of Dr. Russo’s testimony that she diagnosed H.B. as having been sexually abused by defendant. Defendant argues that this testimony was an impermissible expert opinion on H.B.’s credibility.
“ ‘In a sexual offense prosecution involving a child victim, the trial court should not admit expert opinion that sexual abuse has in fact occurred because, absent physical evidence supporting a diagnosis of sexual abuse, such testimony is an impermissible opinion regarding the victim’s credibility.’ ” State v. Bush, 164 N.C. App. 254, 258, 595 S.E.2d 715, 718 (2004) (quoting State v. Stancil, 355 N.C. 266, 266-67, 559 S.E.2d 788, 789 (2002) (per curiam)); see also State v. Ewell, 168 N.C. App. 98, 105, 606 S.E.2d 914, 919, disc. review denied, 359 N.C. 412, 612 S.E.2d 327 (2005) (holding that it was error for the trial court to allow expert testimony that it was “probable that [the *46child] was a victim of sexual abuse” when the testimony “was not based on physical evidence or behaviors consistent with sexual abuse”); State v. Couser, 163 N.C. App. 727, 729, 594 S.E.2d 420, 422-23 (2004) (finding error when the trial court permitted an expert to testify that she diagnosed the victim with “probable sexual abuse” when there was insufficient physical evidence of such abuse); State v. Dixon, 150 N.C. App. 46, 53, 563 S.E.2d 594, 598-99, aff’d per curiam, 356 N.C. 428, 571 S.E.2d 584 (2002) (concluding that it was improper to allow an expert opinion that the victim had in fact been sexually abused when no physical evidence supported a finding of sexual abuse).
In Bush, our Court held that it was plain error for the trial court to permit an expert witness to testify that she diagnosed the victim as having been sexually abused by the defendant. Bush, 164 N.C. App. at 260, 595 S.E.2d at 719. The expert witness, who was also Dr. Russo, testified that a lack of physical evidence was “absolutely consistent” with the victim being sexually abused, because physical evidence of abuse is not always present. Id. at 259, 595 S.E.2d at 718. Dr. Russo testified that she diagnosed the victim as having been sexually abused by. the defendant, stating:
“I was impressed by [the victim’s] sensory recollection. Children cannot fantasize visual and other sensory experiences at the same time and the fact that she could tell me how she felt, how she was feeling that evening, what she felt, and what she did when she realized what was happening, what [the defendant’s] response was when she realized he was waking up, where they were, where the other people in the family were at the time, all of that other sensory recollection was very telling and adds to the credibility of her story.”
Id. at 259, 595 S.E.2d at 718. Our Court held that it was plain error to admit the expert witness’ conclusive statement that the defendant had sexually abused the victim since the only evidence that the defendant sexually abused the victim was the victim’s own testimony and the corroboration of other witnesses. Id. at 259, 595 S.E.2d at 718-19. As a result, “[t]he practical effect of Dr. Russo’s testimony was to give [the victim’s] story a stamp of credibility by an expert in pediatric gynecology[.]” Id. at 259, 595 S.E.2d at 719.
Bush is remarkably similar to the case before us. The only evidence that defendant sexually abused H.B. is H.B.’s own statements to the testifying witnesses. There was no physical evidence that H.B. *47had been sexually abused; yet, just like in Bush, Dr. Russo testified that this lack of physical evidence was “absolutely consistent” with H.B.’s account. Furthermore, Dr. Russo conclusively stated that defendant sexually assaulted H.B. when she testified that she diagnosed H.B. as having been sexually abused by defendant:
Q. I want to ask you now, after you conducted the physical examination and you conducted the interview with [H.B.], at some point in time did you form a medical diagnosis of [H.B.] at that time?
A. Yes, I did, sir.
Q. And what was your diagnosis?
A. My diagnosis was that [H.B.] had suffered from the'sexual abuse that she disclosed to me and her family. And my feelings were that [H.B.] being a three year old child could not fantasize that these events occurred. She could not make them up. Children that young do not have the ability to fantasize or—
[Attorney For Defendant]: Objection.
A. —make up—
The Court: Overruled.
A. —an act like that that they have not experienced. It’s not within their mental ability to do that. So based on what she told me, the consistency of what she told me, what she told the parents, what she told law enforcement was just all very striking, and that I felt like she was — that she did experience that abuse.
Under Bush, Dr. Russo’s expert opinion that defendant sexually abused H.B. amounted to an impermissible opinion of H.B.’s credibility. It was error for the trial court to admit the opinion.
The State argues that defendant has failed to preserve this assignment of error because defendant made only a general objection to Dr. Russo’s testimony regarding the diagnosis. A general objection is normally not sufficient to preserve an issue for review on appeal. See N.C.R. App. P. 10(b)(1). Accordingly, we grant defendant’s request to review for plain error. See State v. Andrews, 170 N.C. App. 68, 75, 612 S.E.2d 178, 183 (2005); see also State v. Black, 308 N.C. 736, 741, 303 S.E.2d 804, 807 (1983) (applying plain error review to the admissibility of evidence under N.C.R. App. P. 10(b)(1)).
*48Our Supreme Court has directed that plain error has occurred when an error “ ‘ “had a probable impact on the jury’s finding that the defendant was guilty.” ’ ” State v. Odom, 307 N.C. 655, 660, 300 S.E.2d 375, 378 (1983) (quoting United States v. McCaskill, 676 F.2d 995, 1002 (4th Cir. 1982), cert. denied, 459 U.S. 1018, 74 L. Ed. 2d 513 (1982) (footnote omitted)). In this case, we find that Dr. Russo’s inadmissible opinion likely had an impact on the jury’s finding of guilt.
A trial court commits plain error when it admits expert testimony on a victim’s credibility because it prejudices the defendant in the eyes of the jury. Couser, 163 N.C. App. at 731, 594 S.E.2d at 423; see also Ewell, 168 N.C. App. at 105-06, 606 S.E.2d at 920, and Bush, 164 N.C. App. at 259-60, 595 S.E.2d at 719. In Couser, the only evidence that the defendant sexually abused the minor victim was the victim’s own testimony and the corroborating testimony of witnesses. Couser, 163 N.C. App. at 731, 594 S.E.2d at 423. We held that it was plain error for an expert to testify that she diagnosed the victim as having “probably [been] sexually abused.” Id. at 730-31, 594 S.E.2d at 422-23. We found .that the testimony likely impacted the jury’s finding of guilt since it was an improper opinion of the victim’s credibility, and “the central issue to be decided by the jury was the credibility of the victim.” Id. at 731, 594 S.E.2d at 423.
Like in Couser, the only evidence of H.B.’s allegations were her own statements. H.B.’s credibility was the central issue in the case, and Dr. Russo’s inadmissible expert opinion lent great weight to H.B.’s credibility. Had the jury not heard Dr. Russo’s inadmissible expert opinion, there is a reasonable possibility that the jury would have reached a different result. In accordance with this Court’s previous decisions on this issue, we find plain error. See In re Civil Penalty, 324 N.C. 373, 384, 379 S.E.2d 30, 36-37 (1989) (“Where a panel of the Court of Appeals has decided the same issue, albeit in a different case, a subsequent panel of the same court is bound by that precedent, unless it has been overturned by a higher court.”); see also In re R.T.W., 359 N.C. 539, 542 n3, 614 S.E.2d 489, 491 n3 (2005).
The State argues that State v. Stancil, 146 N.C. App. 234, 552 S.E.2d 212 (2001), modified and aff’d per curiam, 355 N.C. 266, 559 S.E.2d 788 (2002)), and not Couser, controls this case. Although our Supreme Court found that the admission of the expert testimony in Stancil was error, it held that the error was not plain error because there was overwhelming evidence of the defendant’s guilt. Stancil, 355 N.C. at 267, 559 S.E.2d at 789. Our Court rejected a similar argu*49ment in Couser, where we noted that, in Standi, “in addition to testimony of the victim and other corroborating evidence^] there were two permissible expert opinions that the victim exhibited characteristics consistent with sexual abuse.” Couser, 163 N.C. App. at 730-31, 594 S.E.2d at 423 (citing Stancil, 146 N.C. App. at 240, 552 S.E.2d at 215-16). The victim in Standi also “showed intense and immediate emotional trauma after the incident,” and continued to show such symptoms five days later. Couser, 163 N.C. App. at 731, 594 S.E.2d at 423 (citing Stancil, 146 N.C. App. at 240, 552 S.E.2d at 215-16). We then contrasted this “overwhelming” evidence with the evidence in Couser: the mere testimony of the victim and the other witnesses’s corroboration. Couser, 163 N.C. App. at 731, 594 S.E.2d at 423. Unlike in Standi, there was no other permissible expert testimony in Couser, nor was there evidence that the victim exhibited behaviors that were consistent with having suffered from sexual assault. Id. at 731, 594 S.E.2d at 423.
We find that Couser, and not Standi, controls this case. The State did not present other overwhelming evidence of defendant’s guilt. Dr. Russo’s inadmissible expert opinion was the only expert witness testimony for the State. Although H.B.’s family member testified that H.B.’s behavior had changed since the incident, there was no evidence that this behavior was symptomatic of having suffered sexual abuse. In the absence of overwhelming evidence of defendant’s guilt, we find that the admission of Dr. Russo’s diagnosis was plain error.
We also distinguish this case from this Court’s recent decision in State v. Goforth, 170 N.C. App. 584, 614 S.E.2d 313 (2005). In Goforth, this Court held that it was not error to admit expert opinion testimony that the victims had been repeatedly sexually abused. Id. at 590-91, 614 S.E.2d at 317-18. The expert testified that both victims had physical manifestations of vaginal trauma caused by “intentional” or “not accidental” penetration. Id. at 590-91, 614 S.E.2d at 317. Therefore, in Goforth, the expert’s testimony involved objective physical evidence of sexual abuse. In contrast, the only physical manifestation of injury suffered by H.B. in this case was pain, which is subjective and not independently verifiable. Therefore, it was improper for Dr. Russo to testify that she diagnosed H.B. as having been sexually abused.
Finding plain error, we grant defendant a new trial. However, we elect to address defendant’s remaining assignments of error since the issues are likely to recur upon retrial.
*50II.
Defendant argues that the trial court committed error when it overruled defendant’s objection and permitted L.B. to testify that defendant had sexually abused her twenty-three years earlier. At trial, after the parties conducted a voir dire hearing on L.B.’s testimony, defendant objected to the testimony on the grounds that it was improper evidence under Rule 404(b). N.C. Gen. Stat. § 8C-1, Rule 404(b) (2003). The trial court admitted the testimony, and instructed the jury that “[t]his evidence will be received solely for the purpose of showing that there existed in the mind of the [defendant a scheme, plan, system, or design involving the crime charged in this case.”
Rule 404(b) states:
Evidence of other crimes, wrongs, or acts is not admissible to prove the character of a person in order to show that he acted in conformity therewith. It may, however, be admissible for other purposes, such as proof of motive, opportunity, intent, preparation, plan, knowledge, identity, or absence of mistake, entrapment or accident.
Id. Our Supreme Court has held that, under Rule 404(b), “evidence of prior sex acts may have some relevance to the question of [the] defendant’s guilt of the crime charged if it tends to show a relevant state of mind such as intent, motive, plan, or opportunity.” State v. Boyd, 321 N.C. 574, 577, 364 S.E.2d 118, 119 (1988). However, the admissibility of evidence under Rule 404(b) “is constrained by the requirements of similarity and temporal proximity.” State v. Al-Bayyinah, 356 N.C. 150, 154, 567 S.E.2d 120, 123 (2002). Furthermore, “[r]emoteness in time between an uncharged crime and a charged crime is more significant when the evidence of the prior crime is introduced to show that both crimes arose out of a common scheme or plan.” State v. Stager, 329 N.C. 278, 307, 406 S.E.2d 876, 893 (1991). Evidence that a defendant engaged in previous sexual abuse is inadmissible when a significant lapse of time exists between the instances of alleged sexual abuse. State v. Jones, 322 N.C. 585, 590, 369 S.E.2d 822, 825 (1988).
In Jones, the twelve-year-old victim alleged that the defendant, her stepfather, sexually assaulted her. Id. at 586, 369 S.E.2d at 822. A witness testified that the defendant, with whom the witness formerly lived, had sexually assaulted the witness in the same manner. Id. at *51586, 369 S.E.2d at 822-23. The witness testified that this abuse occurred seven years earlier, beginning when the witness was eleven years old. Id. at 586, 369 S.E.2d at 822-23. Our Supreme Court held that the admission of this testimony was in error since the time period between the two acts was “severely attenuated [and] ‘substantially negate [s] the plausibility of the existence of an ongoing and continuous plan to engage persistently in such deviant activities.’ ” Id. at 590, 369 S.E.2d at 824 (second alteration in original) (quoting State v. Shane, 304 N.C. 643, 656, 285 S.E.2d 813, 821 (1982)). The Court found that the “probative impact [of the evidence] ha[d] been so attenuated by time that it ha[d] become little more than character evidence illustrating the predisposition of the accused.” Id. at 590, 369 S.E.2d at 825.
Like in Jones, the extreme time lapse between the alleged instances of abuse merits against finding that defendant was engaged in an ongoing plan or scheme of sexual abuse. Because the evidence was admitted solely for the purpose of showing a “scheme, plan, system or design,” and because of the lapse of twenty-three years, a significant period of time, the trial court erred in admitting this evidence.
The State argues that State v. Jacob, 113 N.C. App. 605, 439 S.E.2d 812 (1994), controls this case. In Jacob, the victim testified that the defendant, her father, raped her three times when she was ten years old. Id. at 606, 439 S.E.2d at 813. Over the defendant’s objection, the defendant’s twenty-two-year-old daughter testified that the defendant sexually abused her when she was around nine years old. Id. at 607, 439 S.E.2d at 813. A witness testified that the defendant had told her “when my daughters get old enough to know about love, [I am] going to be the one to teach them.” Id. at 609, 439 S.E.2d at 814. We held that the incidents of sexual assault were not too remote in time to show that the defendant had a common scheme or plan to initiate his prepubescent daughters into sex since “the remoteness in time was due to [the] defendant’s having almost no access to the daughters of his first marriage following his divorce. . . . [The victim] was not born until [4 years after the defendant’s divorce], and did not reach a prepubescent age until several years later.” Id. at 611, 439 S.E.2d at 815.
We find Jacob distinguishable from this case. Unlike in Jacob, the State has offered no evidence that defendant did not have any access to his preferred victim during the twenty-three year time span between the alleged instances of abuse. The State has failed to estab*52lish that defendant’s plan was interrupted and then resumed twenty-three years later. The admission of this evidence was in error and should not be admitted at his new trial.
In the alternative, the State argues that L.B.’s testimony was admissible under Rule 404(b) to show identity and intent. The trial transcript reveals that the State did not rely on these grounds when it argued for the admissibility of the evidence before the trial court. Rather, the State relied on the theory that the testimony was admissible to show a common scheme or plan. Since the argument of identity and intent has been raised for the first time on appeal, it is not properly before us. State v. Penland, 343 N.C. 634, 654, 472 S.E.2d 734, 745 (1996), cert. denied, 519 U.S. 1098, 136 L. Ed. 2d 725 (1997); see also State v. Hunter, 305 N.C. 106, 112, 286 S.E.2d 535, 539 (1982) (“The theory upon which a case is tried in the lower court must control in construing the record and determining the validity of the exceptions.”).
III.
The final assignment of error addressed in defendant’s brief contends that the trial court erred when it allowed the State to elicit Gordon’s testimony that defendant possessed pornographic magazines and women’s underwear. Defendant failed to object to this evidence at trial, and asks that we review for plain error. In order to determine whether plain error occurred at the trial court, we “ ‘must examine the entire record and determine if the . . . error had a probable impact on the jury’s finding of guilt.’ ” State v. Pullen, 163 N.C. App. 696, 701, 594 S.E.2d 248, 252 (2004) (quoting State v. Odom, 307 N.C. 655, 661, 300 S.E.2d 375, 379 (1983)).
Under Rule 404(b), “evidence of a defendant’s prior conduct, such as the possession of pornographic videos and magazines, is not admissible to prove the character of the defendant in order to show that the defendant acted in conformity therewith on a particular occasion.” State v. Smith, 152 N.C. App. 514, 521, 568 S.E.2d 289, 294, disc. review denied, 356 N.C. 623, 575 S.E.2d 757 (2002). Such evidence is only permissible if it is relevant to show something other than a defendant’s character or propensity to commit the crime of which he is charged. N.C. Gen. Stat. § 8C-1, Rule 404(b); Smith, 152 N.C. App. at 521, 568 S.E.2d at 294.
In Smith, the defendant was accused of sexually assaulting his stepdaughter. Id. at 516, 568 S.E.2d at 291. Our Court held that the *53trial court erred by admitting evidence that the defendant possessed pornographic magazines. Id. at 521, 568 S.E.2d at 295. There was no evidence that the defendant had shown the victim pornography or otherwise used the pornography during the alleged assaults, and consequently the defendant’s possession of the pornography was not relevant to prove that the defendant committed the charged offenses. Id. at 523, 568 S.E.2d at 295. Therefore, we held that the sole purpose of the evidence “was to impermissibly inject [the] defendant’s character into the case to raise the question of whether [the] defendant acted in conformity with his character at the times in question.” Id. at 522, 568 S.E.2d at 295; accord Bush, 164 N.C. App. at 262, 595 S.E.2d at 720 (admission of evidence that a defendant accused of sexual assault on a minor possessed and purchased pornographic videos was inadmissible under Rule 404(b) and prejudicial at trial).
As in Smith, the State presented no evidence that defendant’s possession of pornographic magazines and women’s underwear played any part in the alleged offenses. Therefore, the evidence was not relevant to prove the charges against him and was merely impermissible character evidence. The admission of the evidence was in error. However, we do not find that the error amounts to plain error. There is no indication that the error had any impact on the jury’s finding of guilt. Nevertheless, the admission of the testimony for the purpose of showing defendant’s propensity to commit the crime was in error and should not be presented at defendant’s new trial for this same purpose.
We deem those assignments of error not addressed in defendant’s brief abandoned. N.C.R. App. 28(b)(6).
