Is the gay gene secretive meaning, you think your straight all your life and then all of a sudden you have interest in the same sex. I ask because normally gays and lesbians know from childhood what gender they prefer. Bisexuals tend to have difficulty identifying with what gender they like. So say we have a straight guy in his late teens, he has been interested in women all his life, all of a sudden he starts to be attracted towards the same sex. So really does the gay gene trigger? or do you believe in the gay gene?
