I think i might be bisexual o_O?

Well you could be. If you keep having these thoughts and feelings than yea, you might be bi. But at the same time you could just be curious right now and that is normal for girls. Plus you might sub-consciously think these thoughts because you know guys are turned on by that? Idk, that is just a guess. Anyway, just keep it cool and as time goes by, see how you feel. Whatever happens, happens.
