That is a great question....
I know plenty of people that would consider me jealous n a women hater..However I have many female friends that I hold dear to my heart.
With that being said I think it is the same thing, that some women click and some women dont...Not to mention if you look at it in technical terms you will find it is the same as men and same as animal that we all are just trying to be more dominant than others.Be in more control, and be held higher...Women just arent as numb as men "oh look my guns are bigger, oh my car is faster, etc....Not jealousy at all, either they dont click or that they are just the better person. Not necessarily that you want to be like the other person or are threatened by them in any way, just that you yourself are better???
