holy shit 29 fucking pages!!!!! im not gonna read the whole thread!
but from what i read in the first post... he did exactly what a horny man would do. and thats take advange of a drunk girl. since the girl could barley walk.. two things could have happen

1. he had sex with a half asleep person
2. they had oral sex

sorry about what happened. the best thing you can do is move on. trying to deal with the problem might just bring more problems.

Later, Alex.
