I just found out my highschool crush is a slut?

[Valy]

Um, you stalk her profile for two years with the intention of masturbating?
Reality check here?!

Look pal, she might be exaggerating, but she's doing stuff with her best intentions: getting experience.
It is normal for her age, as both girls and lads are curious as to what life may bring them. They like the sense of adventure and rebelliousness.

Give this girl a break. Just because she has compromising photos doesn't mean she's a "slut" or a "whore". Sure, she might ACT slutty, but she might be a really nice person with a sweet personality, and do this stuff only when she's drunk (and at that age, it's perfectly normal to be!).

You're obviously not mature enough to handle the fact that nineteen year old girls want to taste the forbidden, so for both of your sake, either forget her, or talk to her and respect her for who she is.
If she was "the girl of your dreams", then grow a pair and talk to her in real life. You can't just go from admiration to "now I hate her" overnight!
