I think most people would understand that "destroy" does not literally mean destroy.

Usually men have the dominant role during sex whilst women prefer to be submissive (though obviously not always the case). Using hyperbolic language is a safe and effective way to demonstrate dominance.

True. People sensationalize to get more views. It's like how people title YouTube videos things like "Hillary Clinton gets smacked down by Obama in debate" when it's just a clip of a routine rebuttal by Obama.

What a load of BS. No, women do not "prefer to be submissive", except in some misguided guys' fantasy lives.

And it really doesn't matter that destroy isn't meant literally - it's still used as a term intent to degrade and humiliate. It's about male power fantasies.

Why do you think books like "50 shades of gray" or so popular?

Hint: Because they are a fantasy.

Women also read romance novels set in Victorian times - are you now going to claim that we'd all like to wear corsets and swoon at the arrival of our heroes?

Also: I don't see guys clamoring to become pizza delivery drivers, either, and yet it's a common porn trope.

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.
