Hey, lost child,
I don't think anyone can give you a label...I do think gay, straight or whatever is about where your sexuality goes naturally. It's not decided by one dream or a few encounters, but day-to-day, where your desires just tend to be drawn. If you're having same-sex experiences, it may be an expression of what you really want, or you may be reacting to other issues, or just experimenting...you'll know that when you're ready to. No pressure.
Welcome to the board--if you'd like to talk more about how you are feeling, feel free to share whatever you're comfortable sharing. The board has been very supportive for me.
