Okay, so I'm going to share with you something that only one person (aside from those involved) know about. TRIGGER WARNING!!!!
I was going out with a guy who has a very high-libido. I have problems with intimacy, so we hadn't had sex. Me, him, and my best friend went out to drink and basically get f***ed up. I was trashed; I had taken at least two dozen painkillers, had half a bottle of booze, and even a little weed. I don't remember what happened, but apparently I engaged in a threesome with my ex and my best friend. I KNOW that they took advantage of me. I broke up with my ex about a week later, mostly because of sexual issues between us. My best friend and I didn't talk for at least 6 months.
Another brief story: The two times that I've been r*ped were committed by the same guy (although I know that's rare). He was a friend of a friend, and I made the mistake of getting wasted around him, when nobody really gave a s*** about who did what to who or if it was consensual. That was my fault. I had a drinking problem; it was bad enough that I got drunk around him, even though he'd already r*ped me once.
You need to QUIT DRINKING, at least around these guys. And, I'm sorry if it's not my place, but I wouldn't hang around either of those guys anymore. If your guy friend didn't stick up for you...that's just messed up.
