I’m a guy,I have never kissed anyone and my 18th birthday is in a few days. Today I told my best friend and he said he’d kiss me if I wanted. I said yes and we ended up making out for a while in his room until his brother came in and saw. I went home after that and I don’t know what to do now. I think I might be gay,since I was aroused by the kissing. I’m hard right now just thinking about it. What should I do?
