Thanks everyone for these words of wisdom. The lack of libido doesn't really affect me, it's more the feeling that I should have it, if only to believe that my marriage is a lively one! Cindy, I was particularly interested in your comments. I come from a family with female pattern baldness. When I was 25, my hair started falling out by the handful. My dermatologist put me on minoxidil (Rogaine). My hair then remained in place and has done so ever since, however, it has not been particularly dense either...until I hit meno. Then, in contrast to other women's experiences, it became very luxuriant. I assumed that it was low progesterone doing this as I could never take the Pill due to severe hair loss.
I decided to stop the Biest with testosterone after one month's use as I don't like the idea of high estradiol (my mother passed away from breast cancer), or high testosterone. However, DH and I decided to do the Nike thing ("just do it") and the atrophy that had been present a couple of months back had most definitely improved 100%. (Still no libido, but I employed my acting skills.) So I think I will carry on with it, only use half the amount, and just see what happens.
