Hey man... I've been right where you are at. I promise you, although it seems confusing right now, you will eventually settle somewhere and know who you are. A lot of gay guys (if they knew me) would be offended by my eventual choice.
I call myself a closeted "Gay Curious". Gay because I know I am not sexually attracted to women and Curious because I have chosen not to live the gay lifestyle, yet would give anything to have a guy to love and take care of... but not necessarily sexually.
Sounds pretty messed up doesn't it? I have had several sexual encounters with guys in my life. The sex part was great, but then I wasn't happy afterwards. I have decided that the reason was because all that was there was the sex... the focus was totally on fulfiling crazy lust.
I don't think there are easy answers out there. There is lots of advice like I am kind of giving right now... but, eventually, you will have to come up with your own conclusion and make your own choices about what kind of life you want. Personally, I think the stigma attached to the whole homosexual thing makes it even more difficult for people to ultimately make the choice that would make them happiest.
I don't know if any of that helped or made it more confusing.
I guess I can sum it all up by saying, "Although life really flies by (and it does!) take your time to really explore who you are and what you want." To me it's better to have one or two incredible experiences than to have dozens that break your heart in the end and leave you feeling empty.
