Getting Back at My Roommate [F]

My college roommate is pretty awful. She’s a great person and is really nice, it’s just that she’s got this girlfriend who sleeps over as often as five days a week and she doesn’t have any respect for me. I do all the cleaning/taking out the trash and I’m too wimpy to just stand up for myself and ask her to help. Her girlfriend sleeping over so often wouldn’t be a big deal if her bed wasn’t about six feet away from mine. Last November, I woke up to the sound of very loud lesbian sex. It was not hot. It was not satisfying. It grossed me out completely. I was extremely upset and I couldn’t believe that the two of them were doing it while I was right there! I spent the rest of the night trying to sleep and completely humiliated. So the next day I finally stood up for myself and told my roommate that I didn’t want anything like that to happen ever again. She apologized and then avoided me for three days, but then everything was just fine.
