It doesn't hurt a man to impregnate a slut. It's less likely to work out then dedicating serious effort into children with a woman you care about, but it still might work, and it doesn't hurt at all to try (traditionally- which is all that is relavent when judging individual humans because you're judging their inbuilt instincts).
For women it's a fundamentally different situation, hence why "hey if men can do it..." arguments are ignorant and retarded. A man could concievably father literally hundreds of thousands of children, he's comparable to a fungus in this regard, it's not his responsibility to be fussy, it's his responsibility to spooge his seed out there as much as possible, like spores on the wind. Women can only have so many children, and each child they have leaves them less desirable to discerning quality males. So it's of pivotal importance that they make sure the people they have sex with truely care for them, are quality specimens of the male homo-sapien, will produce good quality offspring and will stick around to see the offspring reach their full potential by providing food, shelter and general structure for them.
Women have a most extraordinarily important responsibility to direct the evolution of mankind through sexual selection, it's no joke, nothing could ever be more important.
So I have no tolerance for this sex in the city "fuck like men" bullshit women talk about trying to justify their absurdly reckless detrimental and disgustingly slutty behaviour. It's absolutely not acceptable by any means. Please refrain from using your idiotic logic (hey men can do it, it's only fair if women can treat sex like men blah blah) since it is so critically flawed beyond anything your simple brain can comprehend.
Trust that social more's, or "cultural double standards", as you like to call them, know OH so much better than you do. You have no business trying to use your comically inferior reasoning abilities on such a serious issue.
