Hi,
I cannot imagine how devastating having your intimacy destroyed in that way is. What your parents did is wrong, no doubt about it. And, you have the right to have any sexual orientation or no sexual orientation at all, it is your life and not theirs. Sexuality is part of life but some people just do not understand. Nobody can tell you if you are gay or not, but you. Do not allow any anybody questioning your sexuality please, because it is your very core and nobody has the right to question it. I am sending you a big hug
