Your body starts with the assumption of her wanting to get it on. Why? Because if it's wrong nothing is lost.
It's an assumption.
I can go into length. There are a couple of reasons why woman use the strategy of hiding when they are fertile for example, but the main is that she can control by tactics very well how likely she is to conceive.
Usually she is not aware of this herself, but when her subconscious throws her into "woman mode" she will arrange matters to fit to her advantage. Because of this guys do not get much of a say in when how and what. Their strategy is to be always ready, just in case and also to try to monopolize woman.
However the statistic about people thinking that they get 2,5 times as much hit on as they hit on others is similar for both genders.
Of course there are statistical oddities floating around. When everyone claims he is a statistical oddity, you know that you can brush that off as bogus and you don't run a real risk of actually being of the mark.
