Cemar,
Back a couple years ago after I first got on the board and had some early success with MrsGGB, we did have sex every day for a couple of months. That did little or nothing to increase her desire, so I wouldn't count on that doing the trick.

I think Corri et al have a better read on it; desire comes in part from the chemistry created by cool confidence. I think that does a lot more than amped up testosterone does.
