Someone once asked me this, which songs do you personally recommend?
This is a well known song in this category, there are others though...
This is a good concept. Not gonna lie.
I don't know that many. Or maybe I'm weird with those things or something. But this should qualify:
Centhron (f.e. Slutbutt, Cunt) and Suono - fuck me now and fuck me hard, and also Shaolyn - face down :) If you think about it you also know more xD....Agonoize- koprolalie and so on...
"Dirty" by Grendel? and definitely "Sex Sick" by Hocico.
also, even Combichrist has some songs that relate to sex :P
