33 percent of gay males are in a non-committed open relationship. 56 percent of gay males are not in any relationship. This is partly caused by the wandering eye of all males, straight and gay, and partly because society, up to now, has so strongly discouraged male couples, and partly because of the esteem problem gays have. However, the current laws also discriminate against lesbians who are on average much more interested in long term relationships. If we make being gay respectable, all our kids will turn gay.
Sexuality is hard-wired into the brain long before puberty.
You can't change your gender preference just by an act of will. Gays can't make themselves straight. Straights can't make themselves gay. I read three books provided by Reverend Terry Winter on how Christ can reputedly convert gays into straights. The books made no such claims.
