Consider experimenting, but don't feel pressured to do anything you're not comfortable with. Find a guy you trust and talk to him maybe. However, sexuality isn't a choice, and it's not confined to straight/gay/bi. Give yourself time to figure it out, and try not to stress too much. If you like someone and want to pursue a relationship, pursue it! If you find out it's not for you, it's 100 okay. Rarely do people get it right on their first try. Just relax and make sure you feel/are safe.
