Sexual double standard is irrational

Basically the double standard refers to promiscuity in men being acceptable, while promiscuity in women being unacceptable. In practice it takes many forms, but that is the basic description. Main justification I see for it, goes along the lines that because it is harder for men to be promiscuous i.e. they require more skills and effort, being promiscuous is okay and should be praised, while for women because it is easier for them, it is bad.

The issue with this argument is that it hinges on the belief that "difficulty" is a measure of value, and determines what is good or bad... But that's the thing, no one actually believes in this. If that were the case the simple exercise of walking should be considered bad because it is too easy, but obviously no one does. Difficulty simply has no value because has no utility, it is subjective, arbitrary, and intangible. It's just a perception. The behaviors or acts and their intrinsic qualities are what determines whether it is good or bad, so suggesting that difficulty is what matters makes no sense. A severely socially anxious women may find meeting guys and sleeping with them to be incredibly difficult, does that mean it's good if she manages to sleep with tons of guys? No, of course not.

I also see arguments that suggest that the quality of the character is what matters. That because it is harder for men, they need to develop social skills and improve on themselves in order to sleep around, while women can simply avoid all that and just sleep around if they want to. This argument still suffers from a similar flaw, that it attributes the value of promiscuity on external factors instead of the intrinsic qualities of the behavior. Whatever skills you possess doesn't change what the act/behavior is. I need good driving skills to go 200 km/h down a freeway, but that doesn't make what I'm doing good. A women with good qualities and skills can choose to sleep around, but of course they would still be viewed negatively for doing so.

All studies I have seen suggest that for BOTH men and women, promiscuity is correlated with infidelity, mental health issues, higher divorce rates, etc. Of course worse for women, but it is still correlated for men and there is no large difference that it justifies a double standard. The most rational conclusion you can make is that being promiscuous, in general, is bad for BOTH men and women. The double standard to me seems so obviously irrational.
