Well, it seems to me that if you are going to use terms like "sluts" and "players", you are setting a double standard. No one wants to be called a slut, a lot of people would be happy to be called a "player".
Here's the thing. Monogamy is actually contrary to nature. In nature, the male is hard wired to drop his seed into as many females as he can, the female is hard-wired to only select the best males. Most of their young don't survive until adulthood.
Today, we have contraception and abortion, which means we have control of the process. We conquered most diseases.
I suspect, someday in the future, sex will be exclusively for recreation, and procreation will be done in a lab, where the best genes are selected and implanted. We might even have artificial wombs at some point, removing the need for pregnancy altogether.
Deciding to have an abortion is self-control. It's certainly better than the woman who has four different babies by three different baby-daddies and expects the government to take care of that.
