I must say I agree with everyone else. I was rapped when i was 18 by a very close friend and it took me years to actually come to realize that it was rape cause my brain denied it going on.
but no having something like that go on to you was very much not your fault. I am kind of an odd duck in that how I gained back my mental control of being rapped was to get into the BDSM culture. Granted in that in environment things can go badly easily if you are not careful and know everything you are getting into but for me it has helped me a lot.

its not the answer for everyone but everyone has their own way of helping themselves in their lives.
