Having these organic experiences lead to the development of skills which don't exist in isolation, but instead play a role in knowing how to deal with women successfully in the rest of life.

I often hear claims like that here on LW, but they sound very implausible to me. I never had a girlfriend until I was 26 but I'm not under the impression that before then I was deficient in otherwise dealing with female friends/professors/etc. in a way that I no longer am, or in a way that I was not with male friends/professors/etc. (In particular, in most of my late teens and early twenties I had many more female friends than male friends.) Do you (or anybody else who's been making such claims) have any evidence (that could be easily shared on a Web forum) of that?
