Competitive advantage
Some men foolishly attempt to explain female sexuality to women. As a rule of thumb, women know their own sexuality pretty well. However, lying to men and everyone else about their own sexuality is a very important female strategy. This is because, generally speaking, the more overtly sexual women appear, the lower their perceived sexual market value becomes.
On the other hand, a good understanding of female sexuality is part of male sexual proficiency. Lovemaking technique and physical endowment are other elements of it. Proper sexual proficiency is an aspect of sexual market value that does not suffer from advancing age, and it is more personal than wealth. It even has the potential to generate love. Men of sufficient intellectual capacity have a good reason to work on their sexual proficiency.
