I am inclined to agree with much of what you said (though, not all of it). However, you are making a lot of claims without supplying us with supporting evidence. Can you please provide names of books, studies, or links, etc.?
Specifically, for statements where you claim it is empirical fact:
but the empirical facts are that (a) promiscuity hardly requires money, social skills and tactics ("Game") being more important, and (b) most people who are socioeconomically comfortable have little interest in promiscuity after age 25.
If you can't supply external evidence of your claims, then please refrain from making such claims in the first place. However, if you do have evidence then I am genuinely interested in studying up on this. :)
