Is it normal i hate listening to my roommate and her boyfriend have sex?

We share a small room. Her bed is on one side, then there's a space about 10-feet total between our beds. Our desks are either by the window or in the small space between the door and our room. Every single night my roommate brings her boyfriend back to our room around midnight. I have a 7AM class, so I get up early to get to the student dining hall. So I have to get to bed by 11PM. I study in the room since my books are all here. But without fail, around midnight I'm woken up by all the grunting and slamming of her bed against the wall. I can't imagine what the guys next to us must think. I mean, I get it. I'm 19 too. But EVERY night? Really? And why so loud? I mean, I'd be happy to leave the room earlier--like before 11PM. I asked her & she said she works 'til 10:30PM so it wouldn't work.

And I think they're putting on a show for me. The other day I got up around 4AM and he was coming back into our room naked! It's like 4AM & he stands there talking to me while his girlfriend is snoring like 12 feet away. What the hell am I supposed to do with this junior standing there like we're just chatting after chemistry lab. I know he knows I hear them. And what's up with the exhibitionism? Kid's always naked in the room even though it's not a single.

Is it normal I get pissed they think making all this noise EVERY night is somehow impressive and I have to be part of their show?
