I don't know, it's the kind of thing that guys don't take as an insult, but women do. Most women don't think it's a compliment to be told they look like they can handle a dick, because they see it as being called a whore. Which is probably true. On the other hand, if a man is told he looks like he can knock the pussy out, he'll talk about how awesome he is for a few hours.
In any case, a whore would probably take it as a compliment. And if she's happy being a whore, good for her.
Besides, as a great American philosopher showed us, bitches ain't shit, but hoes and tricks, Lick on the nuts and suck the dick.
