Donna M. Piatt (wife) appeals the trial court’s order granting joint custody of the parties’ child but awarding John Piatt (husband) primary physical custody. Wife contends the trial court erroneously: (1) treated her post-separation sexual conduct differently from husband’s post-separation sexual conduct; (2) failed to make findings regarding the statutory factors relating to child custody;1 (3) ruled on the admissibili*430ty of certain evidence; and (4) employed a conclusive presumption that homosexual parents are harmful to their children. For the following reasons, we affirm.
I.
Under familiar principles, we view the evidence in the light most favorable to husband, the party prevailing below. See Wilson v. Wilson, 12 Va.App. 1251, 1254, 408 S.E.2d 576, 578 (1991). Wife and husband were married in July 1989, and their child was born on January 13, 1993. Both parents worked, and child care was provided by Tara Angyal, who is a professional child care provider and a friend of wife’s, Sharon Piatt, who is husband’s sister-in-law, and both grandmothers. In December 1994, the parties separated while remaining in the marital domicile and entered into a settlement agreement under which they cared for the child on alternate weekdays and weekends. During this time, while husband was at work, his mother or Sharon Piatt often supervised the child and her slightly older female cousin. On wife’s days with the child, child care was provided by Tara Angyal and wife’s mother while wife worked. After wife vacated the marital residence in June 1996, the child spent alternate weeks with her parents, an arrangement both parties agree was unsatisfactory.
The parties’ settlement agreement also provided that a custody evaluation would be performed by Dr. Christopher D. Lane. In his report, Dr. Lane recommended that the parties share joint legal custody and that wife have primary physical custody with liberal visitation for husband. Dr. Lane based his recommendation in part on “the assessment of [wife’s] parenting abilities as being demonstrably broader in scope at this time than those of Mr. Piatt and in the perceived greater responsiveness of [the child] to her.” Dr. Lane also testified that his assessment of both parties’ parenting skills and *431commitment to parenting “would be consistent with a high level of devotion to the care of [the] child.”
At trial, both parents presented evidence concerning their post-separation relationships with third parties. The evidence established that husband had been involved in one heterosexual relationship and wife had participated in two homosexual relationships following the parties’ separation. Husband and his female Mend testified that their involvement was serious, and they planned marriage with the full support of husband’s family. Wife acknowledged that she was “experimenting” and still dealing with the issue of her sexual orientation, and that as a result, her relationship with her father had been damaged.
Dr. Lane filed a supplemental report in which he reviewed several studies on the effects of homosexuality on children. He testified that “[t]here seems to be no credible documentation of damage to children” from being raised by a homosexual parent. Dr. Lane also indicated that wife “is still struggling with her own sexual identity,” and her “family is reverberating” from her “very angry estrangement from her father.”
The trial court ruled from the bench, finding that wife “is still in a turmoil, which is continuing and has continued over the last two years. This turmoil is as to her sexual orientation and how her life should go forward.” The court agreed with Dr. Lane that “both parents have good parenting skills. They both love their daughter, and their daughter loves both of them.” However, the trial court expressed doubt about the credibility of wife’s testimony and concluded:
I have to balance these things out. And there is no easy answer, but I believe that the father is better qualified at this point to be the primary caretaker of the child. I believe there is more stability in his surroundings and in his home. There is support on both sides of the family, but there is probably a little bit more support on the side of the father____
*432I am going to make it joint custody, because I do not want anybody to think that they do not have a say in raising the child. The primary custodian will be the father.
The trial court awarded joint legal custody of the child, with husband having primary physical custody and wife having ten days per month visitation plus vacations and alternate holidays.
II. Post-Separation Sexual Conduct
Wife contends the trial court erred in treating her two post-separation relationships as having an adverse effect upon the child, but not so treating husband’s relationship. However, the record discloses no finding that either party’s post-separation sexual behavior had an adverse effect upon the child. Rather, the trial court treated the parties’ post-separation sexual behavior as evidence supporting its conclusion that husband provided a more stable home environment for the child. Consequently, wife’s contention is without merit.
In determining child custody, a trial court is required to “give primary consideration to the best interests of the child.” Code § 20-142.2(B). Because the trial court heard the evidence at an ore terms hearing, its decision “is entitled to great weight and will not be disturbed unless plainly wrong or without evidence to support it.” Venable v. Venable, 2 Va.App. 178, 186, 342 S.E.2d 646, 651 (1986).
In general, a court examines the sexual conduct of a parent to determine whether it has had any adverse impact on the child.2 See Brown v. Brown, 218 Va. 196, 199, 237 S.E.2d 89, 91 (1977) (“in determining the best interest of the child, the court must decide by considering all the facts, including *433what effect a nonmarital relationship by a parent has on the child”). Here both parents’ relationships were facts for the trial court to consider, but the record does not reflect that those relationships provided the basis for the custody award.
The trial court referred to wife’s post-separation sexual relationships and her “experimentation” not as having a direct negative impact on the child, but as manifestations of wife’s inner “turmoil” and “lack of control.” These characteristics have a direct bearing on wife’s ability to provide a stable home environment and to “meet the emotional, intellectual and physical needs of the child.” Code § 20-124.3(3). See Bostick v. Bostick-Bennett, 23 Va.App. 527, 478 S.E.2d 319 (1996) (the degree of stability of the home environment is a matter of concern under Code § 20-124.3(3)).
The evidence supports the trial court’s conclusion that wife’s home environment was less stable than husband’s. The record demonstrates that wife often left the child in the care of others while she pursued recreational trips and activities. She occasionally took the child with her without regard to the child’s bedtime or evening routine. Wife was unsure whether she would remain in her condo after the one-year lease ended. She dated several individuals and admitted to two sexual relationships. Furthermore, wife’s family relationships were strained.
The court contrasted the stability of wife’s home environment with that provided by husband. The evidence shows that husband developed a routine for the child. He maintained his residence in the marital home, where the child had lived her entire life. He was involved in a long-term relationship with another woman and was planning for marriage. He had the full support of his parents and his brother and sister-in-law. His relatives provided day care for the child and her young cousin.
All of these facts led the trial court to conclude that, while it was clear that neither parent was unfit, husband could provide a more stable environment for the child. The trial court recognized the commitment of both parents to the child by *434ordering joint custody, and the physical custody arrangement provided wife with liberal visitation. The parties acknowledged that their previous shared custody arrangement failed. Credible evidence supports the trial court’s award of joint custody with primary placement of the child with husband.3
III. Consideration of Factors in Code § 20-124.3
In its final order, the trial court stated that it had “considered each and every factor under § 20-124.3 of the Code of Virginia, 1950, as amended.” Wife contends the trial court erroneously failed to make findings of fact with regard to each of the statutory factors.
In determining the best interests of the child, a court must consider all of the factors set out in Code § 20-124.3. Sargent v. Sargent, 20 Va.App. 694, 701, 460 S.E.2d 596, 599 (1995). It is well established that failure to consider all of the factors is reversible error. See, e.g., Robinson v. Robinson, 5 Va.App. 222, 227, 361 S.E.2d 356, 358 (1987). A trial court need not, however, “ ‘quantify or elaborate exactly what weight or consideration it has given to each of the statutory factors.’” Sargent, 20 Va.App. at 702, 460 S.E.2d at 599 (quoting Woolley v. Woolley, 3 Va.App. 337, 345, 349 S.E.2d 422, 426 (1986)). We find no merit to wife’s claim that the trial court must make specific findings as to each statutory factor.
Wife also claims the court failed to consider the “age and physical and mental condition of each parent” as required by Code § 20-124.3(2) by failing to give weight to Dr. Lane’s report. Wife’s argument to the contrary, a trial court is not required to accept the opinion of an expert. See McLane v. *435Commonwealth, 202 Va. 197, 205-06, 116 S.E.2d 274, 281 (1960). “It is well established that the trier of fact ascertains [an expert] witness’ credibility, determines the weight to be given to their testimony, and has the discretion to accept or reject any of the witness’ testimony.” Street v. Street, 25 Va.App. 880, 387, 488 S.E.2d 665, 668 (1997) (en banc) (citing Bridgeman v. Commonwealth, 3 Va.App. 523, 528, 351 S.E.2d 598, 601 (1986)). Thus, the trial court acted within its discretion when it declined to follow Dr. Lane’s recommendation.
IV. Evidentiary Issues
Wife contends the court erred in making a number of evidentiary rulings. Given its responsibility to manage often complex and hotly contested litigation, a trial court has broad discretion to determine the admissibility of evidence. See Langhorne v. Commonwealth, 13 Va.App. 97, 106, 409 S.E.2d 476, 482 (1991) (citing Blain v. Commonwealth, 7 Va.App. 10, 16, 371 S.E.2d 838, 842 (1988)).
Wife argues the trial court arbitrarily excluded evidence relevant to the factors outlined in Code § 20-124.3. Some of the evidence to which wife refers was, in fact, not excluded. The other evidence was excluded as irrelevant, too abstract, or argumentative. “Evidence having rational probative value and which adds force and effect to other evidence will be admitted unless some other rule requires its exclusion.” Peacock Buick v. Durkin, 221 Va. 1133, 1136, 277 S.E.2d 225, 227 (1981) (citing Levine v. Lynchburg, 156 Va. 1007, 1014, 159 S.E. 95, 97 (1931)). After reviewing the excluded evidence, we conclude the trial court properly exercised its discretion to exclude evidence which it considered too far afield from the issues confronting the court.
Wife claims the court’s evidentiary rulings were tied to the sexual orientation of the party offering the evidence or asking the question. A litigant is denied due process if his or her case is heard before a judge who harbors “ ‘such bias or prejudice as would deny [the litigant] a fair trial.’ ” Welsh v. Commonwealth, 14 Va.App. 300, 314, 416 S.E.2d 451, 459 *436(1992) (quoting Justus v. Commonwealth, 222 Va. 667, 673, 283 S.E.2d 905, 908 (1981)), aff'd, 246 Va. 337, 437 S.E.2d 914 (1993) . The trial judge made no statement that his rulings were based on anything other than the rules of evidence. The fact that the trial court made a number of evidentiary rulings adverse to wife, without more, does not indicate the trial judge was biased against her. See Stevens v. Commonwealth, 8 Va.App. 117, 123, 379 S.E.2d 469, 473 (1989) (finding no bias despite the fact that the defendant lost 36 of 38 objections). The trial court’s evidentiary rulings were a proper exercise of its discretion and showed no bias against wife.
Wife also argues the court erred in admitting a greeting card as evidence, as well as in reading the card to determine whether it contained hearsay. After husband attempted to introduce the card, wife objected on the basis that the contents of the card were hearsay. The court ruled, “If you are offering it for the contents of the truthfulness of it, sustained.” The premise of wife’s argument is incorrect. As the court’s statement makes plain, the trial court did not admit the card, but ruled it inadmissible.
Wife’s argument that the trial court erred by reading the card also fails. First, the court had to read the card to rule on its admissibility. Second, the trial court is presumed to have excluded inadmissible evidence from its consideration, and wife has offered nothing to rebut this presumption. See Adams v. Adams, 233 Va. 422, 429, 357 S.E.2d 491, 495 (1987) (citing Eckhart v. Commonwealth, 222 Va. 213, 216, 279 S.E.2d 155, 157 (1981)). The trial court properly exercised its discretion in ruling on the admissibility of the card.
For the foregoing reasons, we affirm.
Affirmed.
. In her brief, wife attempts to enlarge the issues on appeal to encompass a claim that the evidence was insufficient to support the court’s ruling. We limit our review to the questions presented by wife. See *430Carbaugh v. Solem, 225 Va. 310, 312 & n. *, 302 S.E.2d 33, 34 & n. * (1983). This Court, as well as the opposing party, must be able to rely on a party’s statement of the questions presented. See, e.g., Rule 5A:25(d).
. This standard applies to both heterosexual and homosexual conduct. See, e.g., Ford v. Ford, 14 Va.App. 551, 555, 419 S.E.2d 415, 418 (1992) (upholding custody award to homosexual parent because the child was not exposed to the "illicit nature” of the relationship); Sutherland v. Sutherland, 14 Va.App. 42, 414 S.E.2d 617 (1992) (upholding custody award to heterosexual parent because the evidence did not show that the parent’s sexual conduct had an adverse effect on the children).
. Wife also contends that the court’s disparate treatment of the parties’ sexual conduct in the absence of evidence of an adverse effect of that conduct gives rise to an inference of an unconstitutional "conclusive presumption that homosexual parents are harmful to their children.” In light of our holding that the trial court made no finding of adverse impact and examined the parties' sexual behavior only as it related to the stability of their homes, wife’s contention is not supported by the record.
