Body Agenda is a shorthand for describing our instinctive sexual desires and instincts that shape our mating habits and sexual strategy. They differ between men and women and that's okay. To quote Athol Kay:
...your body has its own agenda that it’s pursuing… it wants to make babies… and your highly intelligent homo sapiens brain is in fact a tool it uses to get that job done. To be sure, we can think logically and make decisions, but we’re not nearly as in control of ourselves as we’d like to think we are. Hormones and neurotransmitters are our bodies’ way of telling us what to do.
