Existing cross-sectional research suggests associations between physical and sexual abuse in childhood and same-sex sexual orientation in adulthood. This study prospectively examined whether abuse and/or neglect in childhood were associated with increased likelihood of same-sex partnerships in adulthood. The sample included physically abused (N = 85), sexually abused (N = 72), and neglected (N = 429) children (ages 0-11) with documented cases during 1967-1971 who were matched with non-maltreated children (N = 415) and followed into adulthood. At approximately age 40, participants (483 women and 461 men) were asked about romantic cohabitation and sexual partners, in the context of in-person interviews covering a range of topics. Group (abuse/neglect versus control) differences were assessed with cross-tabulations and logistic regression. A total of 8% of the overall sample reported any same-sex relationship (cohabitation or sexual partners). Childhood physical abuse and neglect were not significantly associated with same-sex cohabitation or sexual partners. Individuals with documented histories of childhood sexual abuse were significantly more likely than controls to report ever having had same-sex sexual partners (OR = 2.81, 95% CI = 1.16-6.80, p = .05); however, only men with histories of childhood sexual abuse were significantly more likely than controls to report same-sex sexual partners (OR = 6.75, 95% CI = 1.53-29.86, p = .01). These prospective findings provide tentative evidence of a link between childhood sexual abuse and same-sex sexual partnerships among men, although further research is needed to explore this relationship and to examine potential underlying mechanisms."

THE FACTS
According to the American Psychological Association, "homosexual men are not more likely to sexually abuse children than heterosexual men are." Gregory Herek, a professor at the University of California, Davis, who is one of the nation's leading researchers on prejudice against sexual minorities, reviewed a series of studies and found no evidence that gay men molest children at higher rates than heterosexual men.

The National Health and Social Life Survey (NHSLS) 1.51% of the population of the US identify as GLBT, whereas other studies put this figure as high as 8% (Fay et al, 1989). However, statistics for people abused in childhood are significantly higher that this, with reliable estimates given for child sexual abuse to be 16% for males and 27% for females in the USA (NRCCSA, 1994).
Therefore, if there is a causal link between childhood sexual abuse and identifying as GLBT later in life, then why arenÂ’t the figures for the number of GLBT people in the population reflected by the abuse statistics? There are significantly more cases of sexual abuse than there are people that identify as GLBT (Macmillan, 1997), and furthermore, the vast majority of persons sexually abused as children are heterosexual (Keith, 1991).
In addition to this, virtually all statistics agree that females are more likely to be sexually abused in childhood than males are - and yet, and yet there are proportionally more men that identify as being gay than there are women who identify as lesbian (Hite, 1991; Janus, 1993, Jefferson, 2001).
The problem with the believe that abuse causes homosexuality
Conclusion
The empirical research does not show that gay or bisexual men are any more likely than heterosexual men to molest children. This is not to argue that homosexual and bisexual men never molest children. But there is no scientific basis for asserting that they are more likely than heterosexual men to do so. And, as explained above, many child molesters cannot be characterized as having an adult sexual orientation at all; they are fixated on children.
