Because no man wants to think about the man! And porn is marketed to men. There's a reason he's called the "stunt cock." Quite a few men get off on the idea of HER wanting it. SHE wants the huge cock, she is insatiable. The idea is that the woman/women is a sexual beast who wants you so badly ... which is what the man behind his computer/TV wants because most porn watchers are not indulging with another viewer. The man always must orgasm, but no male viewer wants to see him any more than possible. See also, POV porn.

So, why not "slut loves his cock"? Why "destroy"?

There are a lot of videos labeled with some variety of "slut loves cock". The problem is there must be millions of these videos and they all have substantially the same content - two people engaging in sex.

Producers have to have some way of making their product grab your attention, and "two people fucking" isn't going to do it.
