My mom is having loud sex, ehat do I do?

My mom's boyfriend comes to have a "sleep over" with my mom every Sunday. Our house is very small and my mom sleeps in the living room while i have my own room. My room is right next to the living room. I'm 16 and i sometimes i wake up, because of the voices my mom and her boyfriend makes. I always have to put on my headphones and listen to music so i wouldn't hear the moans and slaps. What do I do? Because of this, i'm always sleepy in school and I feel hurt because i would't do something like this with my girlfriend/boyfriend if my other family members are at home. I feel really bad and disrespected.

(Sorry for the grammar mistakes, i'm from finland and lazy)
