A change in libido for women is difficult to discover a cause. One reason is that doctors don't tend to take a woman's decrease in sexual drive as serious as a mans.

With the little information you have given there isn't any way to figure out what the problem could be related to. Alot depends on age, health conditions that you may have, any medications you may be taking, etc.

I read a recent study, one that did study women's libido, linking decreases in hormones (especially testosterone, yes we have it to *smiles*) to a decrease in sexual drive.

What you have given is a symptom of many things. My suggestion is to make an appointment with a doctor. If this doctor dismisses or doesn't seem concerned about your problem, find another.
