I know. But my parents pay the rent so it'll have to be about the same price. And I don't really want to be like "Um, so like I need to move cuz my roommate keeps bringing this girl over and they make jungle noises at night so I can't sleep, especially because I'm a hopeess porn addict. Hope you understand."
BTW I survived the night.
I'm going to have a talk with him in which I will make it clear that if he doesn't respect me and keeps bringing this slut over, then I will move out without telling anyone and I will leave them responsible for my part of the rent. I can do that because I never signed anything (the whole arrangement is shady to begin with).
Oh, and if he does then I'll make sure to throw her out on the street in the middle of the freezing night regardless of what she's wearing. Gotta show that I'm serious, you know. Then he'll get all upset so I'll just smash his face in with her whore-boots.
OK, so it probably won't happen that way, but a man can dream, can't he?
