> "Why aren’t women displaying more of this “genuine desire”?"

Mostly because they seldom feel that way.

Of course it's also because of the other reasons you mentioned (e.g. being repressed by society), but first and foremost, women seldom feel that "fire" inside.

Why?

1. Well, one reason is that women have lower testosterone levels than men (10 times less on average). Since that hormone is the main responsible for sexual desire, women just have less of that drive to begin with.

2. Women are less attracted to men than vice-versa. There have been some studies confirming that, on average, men find 80% of women desirable, while women find only 20% of men attractive. Therefore, a woman seldom meets a man who she really finds attractive and sexually enticing.

3. Add to the above all the repressive messages from education and society, and it's clear why women are enveloped by desire way less often than men.
