After nearly twenty years, I'm still trying to figure out why I'm a bisexual. In HS, being on the swim team and seeing my other buddies in the showers after practices and meets, I knew I was larger than most but never really gave it much thought. Graduated HS as a virgin except for a lot of blowjobs. Girls I dated weren't opposed to giving me head, but flat out refused to fuck, so my experiences were less than satisfying. Most of my freshman year in college was basically the same. I wasn't really interested in guys and wasn't the least bit curious. That is until after a team party where a couple of seniors on the team got me shitface drunk and had their way with me. What followed the next morning was unbelievable. Up until that time I hadn't even thought about giving another guy head. Tho, I'd had blowjobs from other guys prior to that, the mere idea of returning the favor really grossed me out. That morning was also the first time I'd put my cock up another guy's ass and much to my surprise found that I really enjoyed that too. Still years later, I've never bottomed for another guy and will probably get flamed for saying as much, but really don't want to either. I know a lot of you, knew you were gay and had inclinations or experiences at a much earlier age. That's fine, but my question is really posed for those of you that came out after HS. So like, the title says, I'm curious about whether or not you feel that your first experiences involving penetration influenced your current orientation.
