TRP justifies the "slut vs. stud" double-standard by claiming that women are affected by high partner-counts while men can basically have as much sex as they want with no statistically significant negative consequences. They say that women with a high number of sex partners, accumulated prior to marriage, are much more likely to get divorced. In particular, they cite this report, which claims (correctly): "We found that the more sexual partners a woman had had before marriage, the less happy she reported her marriage to be. This association was not statistically significant for men."

Indeed, TRP is correct: the more premarital partners a woman has, the less likely she is to be satisfied with marriage. Additionally, they are more likely to get divorced. Men, on the other hand, seem relatively unaffected...

HOWEVER... I found myself a bit skeptical. There's no way the number of previous partners a man had prior to his marriage has literally no effect... So I did some digging.

Turns out, the more partners a man has prior to his marriage, the more likely he is to cheat on his wife. In general, men are much more likely to commit infidelity than women, but the odds increase even more so as he racks up more partners. The data can be found here. (EDIT: this source is nothing but a blog which has compiled data to make it easier to interpret. The original, uncondensed study can be found here)

However, this is true of both men and women. Each of the sexes increases their odds of commiting infidelity for each partner prior to marriage.

But men become increasingly dissatisfied with the sexual aspect of their marriage for every premarital partner they had, much more quickly than women. For women, each previous sexual encounter increases their chances of being sexually dissatisfied by 3.9% per partner. For men, it's 5.3% per partner.

That means that if a woman has 10 partners prior to marriage, her chances of being sexually dissatisfied with her husband are 39%. For men, 53%. Therefore, men are indeed affected by slutting around, but in a different way. The first study, oft-cited by TRP, asks men and women about overall marriage satisfaction and found a correlation between women and high partner counts. The second study asks men and women about sexual satisfaction and found a correlation between men and high partner counts.

In a nutshell: A man is much more likely to be dissatisfied with his wife sexually if he has a high number of previous partners; conversely, a woman is much more likely to be dissatisfied emotionally with a high number of previous partners.

Additionally, although men are generally much more likely to cheat on their spouses than women, they are even MORE likely to do so if they decided to ride the pussy wagon in their youth.

So, there you have it. Both men and women are statistically affected by slutting around. With every premarital partner, women are more likely to get divorced, while men are more likely to feel sexually dissatisfied (which would explain why men are more than twice as likely to have extramarital affairs). Stop pretending that men who sleep with a bunch of women are somehow better than women who sleep with a bunch of men.
