If it is the female, not the male, that determines the condition of the animal family, that means the males must be ready to fuck whatever female takes interest in them.

That would explain the variety of porn the males consume(did you know that even shemale porn is mostly consumed by heterosexual males? Crazy world) compared to the singular female ideal of a perfect mate we all know so well from romance novels.

(I know comparing porn to romance novels is unusual but good luck finding romance for males or porn for females)

This would also explain the male desperation to fuck seemingly anything.
