It has nothing to do with the actual people, but the act of sex itself that is turning you on. In my previous apartment a girl moved in upstairs and had loud, bed-squeaking sex with her guy on an almost predictable basis several nights a week.

One time, a friend was kipping at my old flat My flatmate's bedroom was right next to the living room and the wall separating the rooms was like paper. I wouldn't let it bother you how "normal" or "weird" or whatever this is. Bookcases dont have ears, they just hold books.
I posted my question here, because I suspected that other people might actually enjoy it too, but just won't admit it.
We sometimes visit a famous hot springs and the rooms have rather thin walls. It's a way of being creative which is good. Sometimes you'll see those horrible snotty letters people leave complaining that they can hear other people having sex. Happened all the time back in my college days living in an apartment. Sometimes my wife will get off for me while I am in the next room
