I think there a are a fair number of women who aren't all that interested in sex. As a college professor, you often have students come in for 'relationship counseling' - grad. students too, believe it or not. I've had several women say they are just not that interested in sex but love their boyfriends, yada yada.

Androgen levels are non-zero in women and vary somewhat. As a physiologist, I naturally guess that would be part of it.
