Men and women are, in the broad sense, equal but quite dissimilar. They have vastly different selection criteria for potential mates; assess members of their own gender upon meeting quite differently; and there’s an evolutionary uniqueness in it being females that engage in dramatic sexual displays instead of the males.
Strange as it might sound at first to a great many people, these gender-based differences also extend to even choosing what underwear to don on any given day.
As you can see the process of choosing what underwear to wear is vastly different between men and women. Anecdotal evidence also suggests these disparate processes are so different from each other that members of each sex can’t even understand the process of the other. 😆
