<human>: I rent a small house with two other guys.  We each have our own room, but sound travels pretty well.

Housemate 1: He's not too loud, but his headboard is against my wall.  When I was going to ask him to move his bed a bit, Housemate 2 and his girlfriend said, "Nooooo.  Let it happen."

Housemate 2: He's the main culprit.  His girlfriend is loud every single time, and they sometimes have a friend join them, and she's loud, too.  They do very little to hide what they're doing, and I get the impression that they want us to hear.

Now, I'm not a prude.  I consider myself relatively adventurous as well, but one thing that I do not like is hearing other people have sex in my house.  I understand that it's going to happen, but I just think that it's inappropriate for me to be hearing something I'm not a part of.  It makes things incredibly awkward in the house for anyone else that's here.  Housemate 1 and I have trouble hanging out or doing anything, because you can hear them literally wherever you go in the house.  I can't even cook dinner right now, and I don't know how to ask them without sounding like a huge prude.

Summarize the given text in a few sentences.
<bot>: My housemates (particularly one) fuck really loud and often, and I want them to shut up.  What do I do?
