This is part experience, part response. To the guy who wrote that women have no sex drive, I would say that he is generalizing far too much. It actually made me cry because I have such a strong sex drive and because of my job situation, I have few opportunities to express it. I'm single and think about sex very frequently.
Most nights, I read Solo Touch and bring myself to two amazing orgasms, all the while wishing I had someone to share them with. (I can have two orgasms and occasionally a third, but then am too sensitive to continue.) Anyway, my main point is, there are plenty of women with a high sex drive. I'm sorry you have been with some who hadn't, but don't give up.
