Roommate frequently has loud sex. How to talk to her about it?

I’ve been friends with my roommate for a year, and she’s very passive. Her girlfriend is over all the time, and it’s starting to get really annoying. I don’t mind her girlfriend coming over/spending the night like 1-2 times a week, but she’s over here almost every other day. I have the basement as a room, so I don’t have a door - I have curtains in place of a door. And my roommate’s room is next to mine. I hear them having loud sex all the time. So I put in headphones and/or turn my tv all the way up, but I can still hear them. I sleep with my headphones in and sometimes their moaning wakes me up. I’m not sure what to do because if I talk to her about it, she’s going to think it’s a personal attack.

I feel like I’ve compromised enough on my end - if they’re too loud, I’ll either put in headphones, turn my tv up to the max, or sleep on the couch upstairs

I am a college student. Moving is not an option
