Nothing wrong with ladies playing the field but it's not an accomplishment for a woman to get dikked down.
The whole "a key that can open every door is more valuable than a lock that opens for every key" proverb sounds sexist as hell but it's still kind of true. Plus women value experienced men more than awkward/virgin men, so they contribute to that double standard anyway.
