I don't think i'm gay.
O.K. so I'm a 19 year old male and I've always been pretty sure I'm straight, it's very easy for me to get turned on by girls. But for the last 2-3 years I've noticed that I think about men's genitals really often, not in a sexual way really. Just what they look like such as size, shape, circumcision and how they deal with them. What do you think about this, any advise?
