I think the "inborn preference" can be a bit more than being comfortable. For example when a gay man has had a lot of exposure to women, but his penis has never gotten hard when in the company of a woman no matter what they do together. Can he choose to marry a woman and stay with her all his life even though he can't get aroused sexually with her....? Certainly. Perhaps he can use Viagra, cialis, levitra etc. But just because he makes that decision to be with her is not going to change his natural ability to respond to her sexually.
It's the eternal argument of nature verses nurture- probably some of both.
