Roommate Has Crazy Loud Sex??


My roommate will have guys over and have crazy loud sex with them. I’ve asked her to keep it down three times now but she denies sleeping with them... she will have them over right before I am about to go to bed and we share a wall. None of my other roommates have been home while it’s happening. What can I do? Our landlord is friendly with her, should I tell her? Thoughts? :)
