"...how much sperm was "stripped" during ejaculation weren't nearly as effective at it as those our currrent culture would describe as "fat"."

          Males in current industrialized cultures are victims of advertising and consumerism to the point that their cognitive levels of sex drive seek thinner women than their animal levels would normally think to be desirable.

          At least that's what I get from the posting, and I think it's correct. I think modern men would rather be seen in public with women who are thinner than those women with whom they would rather go to bed.
