It's definately not a choice. Im not sure if any of you will agree with this but I personally think I was genetically predisposed to being gay. My mom was a lesbian, although she did hide it for many years because she had certain problems. And no, I wasn't raised by her I have a guardian mother, so it is definately not nurture. It is Nature. Im not saying there's a gay gene, but its possible that there is a gene that is more likely to have somone be LGBT.
