If non-monogamy is equally beneficial to “both” sexes (for purposes of sexual reproduction, I’ll stick with “both”), why don’t men vocalize during sex as much (or perhaps they do, just not as continuously) as do women to demonstrate their sexual health etc. and attract other women?

Other than “sperm wars”, which I don’t think is necessary to explain human female vocalization, what asymmetry am I missing?

Eve Ensler also includes female sexual vocalization in some versions of “The vagina monologues”, but in much more fun and non-academic terms.

I stop to miau to cats.
