While I think abuse or sexual encounters before that age may result in your being more confused about your sexual identity, I don't think it "makes you" one way or the other. I had some huge "daddy issues" growing up and feelings of abandonment so I essentially was a slut - didn't matter girl or guy. I experimented both ways and liked both. However, now that I have done some soul searching I realize that I really am straight. I was confused for a long time but finding out who I really am is what helped me out.

Plus, I think early teens is when most people (if they do) feel a little confused. I think everyone goes through a time when they are sexually developing, hormones are racing and you don't know your *** from a hole in the ground lol. It's perfectly normal and doesn't necessarily mean you will be any certain way as an adult.
