Prostitution is a memorial to the fragility and vulnerability of the men. Most "porn" (whatever that may be) is as well. Because hormones and other bits of nature push males to have sex quickly and often, their 'needs' exceed those of the female of the human species. Women exploiting that merely use what is offered to them by their surroundings.
Men still have so much to learn!
Women are just better at self-control, is all; the consequences of sex are much greater for them than it is for horny boys and men. They are just as 'horny', if not more so, and even more avid for human contact than males, who would be just as satisfied with 'hit and run' than hanging around afterwards. Most men are stupid and untrustworthy re relationships, and women learn that early, at least most do.
FYI, Amazon's biggest online sale category is sex toys, as in dildos and other fun things for women; apparently those are over half its revenues.
I hate to break it to you, but most women are NOT "just as horny" as men, and not in the same way. However many times we are all told that women are just like men when it comes to sex, it isn't true and never will be.
There are different biological imperatives. For men their biological imperative is to spread their sperm to as many females as possible. For women the biological imperative is to obtain the best sperm for their individual egg.
Of course there are; doesn't make it all purely sexual in nature; some women are more sexually attracted to 'bad boys', but when it comes to selecting mates to father children or for long term relationships, yes they have different criteria in play there. And you confuse 'sperm' with 'lust'; they aren't the same thing.
