Perhaps, but if you don't know, then I can't know either. Please consider therapy to help you find out more about yourself.
What do you think? Am I bi?
In your situation I would be confused too. I have a relative, 15, who just announced she is gay. Not everyone in the family would deal with it we'll so they aren't being told. As for your situation, you really need counseling to help you understand your sexual orientation, and to deal with the day to day adjustment as you learn.
