I'm sorry that happened to you, although I've never experienced that (yet).
I tend to play many games that are targeted mainly for guys (CoD, TF2, Dark Souls, Skyrim, Assassin's Creed, that sort of thing), and I've made a lot of best friends who are guys. I usually never tell my real gender, though. I just play along with the 'There are no girls who play violent games' rule.
