are you serious? being gay or straight is something you are born with, some people feel an affinity to men, some to women, its just how your brain is wired, theres no way to choose. some people, however, choose to supress the feeling, but never feel fully fuffilled with the one they choose. for example, my gf's mom's are lesbians, the mom who didn't birth her was married before and had a child, but just didn't feel fufilled with a man. My best friend's mom was married to his dad for 17 years, had two kids, then felt it wasn't right, now she has a partner instead of a husband
