Sorry I didn't see your replies earlier. The email notification doesn't always work.

Maybe I should be happy to be losing all interest in sex. When I was younger, I used to wish I could have no interest in sex, so that I would have more time for productive pursuits. Now that I'm finally getting my wish, I feel lost. I keep thinking I should feel interested, but why should I?

This reminds me of when I quit drinking. I had so much time, because I wasn't drinking, but I didn't know what to do. I would just stare at the wall and feel sorry for myself. Eventually I filled that gap in my life with other things that I value more. Maybe the same will happen with my plummeting libido

It is weird how suddenly it has happened. Probably I should get a physical. I hope I will, but I have such bad luck with doctors. *sigh*
