Sexuality is a complicated subject. The only way to truly find out who you are is to experiment with other guys. If you don't like your experiences with them, then your fears will lessen or better yet, go away.

If you do end up liking guys, then you have answered your questions and thoughts. Just to let you know, there are many men who experiment with other men. They later find out they're not bi or gay at all. This is something you will need to find out for yourself by having encounters with other guys.
