SEX: Why does it sell?

Sex has been an integeral part of forwarding the continuation of species throughout time, but how has stimulating the idea of mating become a selling point?

Within the animal kingdom, males are predominantly the more decorated, as opposed to females. However, when it comes to humans, although men and women are sexualised, women tend to be heavily sexualised and marketed towards. This is something that has always sparked my interest.

Is sex’s marketing use simply a construct we as humans have placed upon society, or are we naturally seeking to see things that are more sexual as more engaging?
