Noisy neighbors

My husband & I bought a condo & unfortunately we are on the second floor below another couple. The couple above us like to have very rough/loud sex multiple times a night making it very very hard for my husband & I to fall asleep/stay asleep. (I can hear them right now) Would I be rude asking them to keep it down? I understand people have sex but be courteous of who's around you & don't do it ALL NIGHT when you know people sleep right under you.
