I disagree because - no, I don’t think (in reverse) - a man who sleeps with 101 women in a day is admired or respected by society today.
I think you're right that there has started to be a shift perhaps, in thinking with regards to the perception of men who sleep around with the current generation, but I think in terms of social penalties, a man in such a position still wouldn't be subject to the sexual judgement that a woman in the same position would be. Nor would he think himself diminished by his previous sexual experiences, which means he would be far less likely to experience a mental schism and see himself as used, or damaged goods, or exploited. His relationship prospects would also be far less likely to be affected. His mental health would likely stay intact.
And the difference in how a man and a woman would both filter these previous sexually liberal experiences come down to the fact that a woman's worth (as you can see from the thread) is still tied to that of the male sexual desire. She has no agency in the face of this desire, even if she is manipulating it, or exerting power over it. She can only be a victim at best.
Essentially women are judged via the penis. Both if they can still attract the penis, and paradoxically, whether they've experienced a lot of penis.
Which ties in with your second post about women wearing makeup etc. Again it because the notion of women's self-worth is intrinsically tied to the male desire. Women have worth if they are desirable to other men. There is currently another thread running discussing all the things women are putting themselves through in order to remain looking as young as possible. Why? Because women being found to be funny, intelligent, interesting, kind, generous or warm, doesn't ultimately matter. What matters most is how desirable she is to men and how many men she's had and many she can still get. That defines her worth.
This woman has a personality but people have called her a slut. You mention harm, but perhaps it is prevailing ideas and notions around female sexual initiative that help engender this harm, and a lack of safety.
Extending this argument on women's worth being tied to the male penis, or male desire, perhaps this is why older women seem to have no value, unless (going by the Grandparenting threads) they are volunteering to look after their son-in-law's offspring, thereby facilitating the penis by proxy.
(I am pushing ideas here! But it makes a sort of sense)
