LOUD ROOMMATES

You know what pisses me off..... LOUD ROOMMATES. Ok I'm not talking about playing loud music, talking loud, etc. that I can handle. It's loud sex. A roommate of mine always brings his girlfriend home to have sex. Which hey, good on you your getting "some". But the problem is that he always thinks that no one can hear the noises coming from his room after the music stops, but actually everyone knows exactly what going on. It is a little hard to study, hold a conversation with another people, etc... In the house when there's so much love making going. If he could just keep his love making noises down to a minimum it would be greatly appreciated........

If anyone has any suggestions on how I can approach this awkward love making situation it would be greatly appreciated. Thanks :).
