"...We can say “chosen” because the vast majority of gay men have had intercourse with women. As a four-year study of 128 gay men by a UCLA professor of psychology revealed, “More than 92 percent of the gay men had dated a woman at some time, two-thirds had sexual intercourse with a woman.” As of now, the one theory we can rule out is that homosexuals are biologically programmed to be homosexual. Despite an understandably great desire on the part of many to prove it (and my own inclination to believe it), there is simply no evidence that homosexuality is biologically determined.
