Picworm, I do believe women are very horny. However, I think women have different priorities. Particularly women with children.
Which is why WL's are great, our number one priority at work is sex. We are thinking about it, many more hours of the day then most women. However, if you were to ask your partner/girlfriend/wife to think about sex every hour on the hour, by the time she arrived home she would be one lusty lady.
The other thing to consider is the stigma associated around a "lusty" woman. Women are to appear sweet and demure, or so society demands. Luckily things are changing and women are beginning to reclaim their sexuality once more.
