I think Athol's MAP is applicable to both men and women - it's essentially taking personal responsibility for the outcome that you desire. As such, women who find themselves in sexless marriages with husbands who have little desire can benefit from implementing it - they will benefit whether or not their husband becomes more sexual or not. Because when you start to take 100% responsibility for yourself and the outcome you desire, you have taken back the control you have so unwittingly been giving to a non-responsive spouse.
Here's also a good book for women that have husband's who aren't interested in sex. Gives a lot of clarity on the various issues that can result in a man who doesn't want sex, and a view in to the fact that it is not that uncommon of a problem:
