This is why "Chads" are celebrated and "sluts" are not.

Since women have relative preferences (your value is determined by your peers), men are in constant competition with each other. Once a woman enters the dynamic it becomes a dick swinging contest because they know they're being compared against. This is part of why men can't really be as vulerable with each other. If men were as affectionate with each other as female friends are, women would assume they're gay and disqualify them. This constant competition and evaluation makes it harder for men to be socially and sexually successful.

Women on the other hand are not equally competitive. If you're the unattractive friend, you might just find you're getting asked out MORE because you seem more attainable. This lack of competition between women makes it easier for them to find relationships with men and friendships with each other. And due to the "Women are Wonderful" effect everyone is biased towards women (both in relationships and friendships). So women have a natural advantage in the social & dating world.

This means their social and sexual accomplishments mean very little compared to men's. I'm way more impressed by an average dude scoring with 3 women in a year than an average woman hooking up with 30 dudes. And I'm way more impressed with a man who becomes popular and achieves a decent social following (in person or digital) than I am with a woman who does the same. When a man accomplishes these things, we know he most likely had to work for it (be funny, be a leader among competitors). With the woman, we know she's at an advantage and likely didn't have to work as hard. Thus the man's social and sexually accomplishments are worth far more.
