I was aware of masturbating for the first time (might have before but wasn't "aware") when I was 17 and after my orgasm (speaking of TMI :-) I had to figure it all out, "Oh, that must have been masturbation" LOL I was just a little naive/sheltered? I was mildly abused when I was 10 by someone who worked for my family but I only knew it was "wrong" didn't know why/what was going on. I didn't think/feel "sexual" until maybe 13 or 14 when my next door neighbor boy (2 years older than me) was messing with me.
