roommate

sooo my somewhat boyfriend and I have a lot of sex..well I just got a new roommate and I'm scared she can hear. I know "who cares" right? well I care because I know if I were her I wouldn't want to have to listen to that. plus we don't know eachother super well. I just feel like it's awkward. and my guy thinks it's funny because he knows how shy I am about it so he loudly says stuff like "we're gunna have sex" hahaha idk what I should do. ):
