Menopause, perimenopause, childbirth and breast-feeding can all cause a woman's sex drive to shut down.

I'm not a Twitter fan. I do it because I feel responsible to the two million people that follow me, but Twitter to me is just another thing I have do. And it's mostly a place for people to attack and abuse you. I don't really get much out of it, personally. I get hundreds of demands to answer the kind of medical questions that require three years of treatment to assess, yet people are furious when I don't solve their problems in 140 characters. It's really stunning.
