Be grateful, man!
You've been obsessing about this too long.
Sit down and talk with your physician about fears. If you'll forgive my frankness, talk with him/her and some wise adults (maybe even dad) about your emerging sexuality and how you've explored. By your age, we've all made mistakes. Embrace being a man, decide how you want love to be for you, and cherish adult love while resolving to be safe ; kind.
