Women aren't the pursuers or choosers though, seriously your level is indoctrination is strong, I've already pointed out that women are only the "choosers" in these modern times and my point is going over your head, consensuality and women having a choice, is a relatively "new thing" for humanity, its not natural, In some data sets around 80+% of women have reported orgasm during rape, it happens whether they choose their mate or not so your point of orgasms being an idicator of women pursuing mates is a non-point they have never been the pursuers, they are the object acted upon not the subject, women choosing is an abnormality that only came into existence as humans advanced
The female orgasm may very well have been "evolved" to make the process of forced intercourse more tolerable, the women who were more likely to experience pleasure from rape, were less likely to resist and be killed, and therefore more likely to survive and pass on their genes
You are asserting that because orgasms exist, it clearly exists for mutual and consensual reasons, I'm stating that asserstion is false, if you look back at history, women never really had a choice, and yet they still had orgasms
So one sex being "frigid" isn't an evolutionary negative, so long as that sex isn't as physically capable as the other, which is the case for human males and females
