As someone who is in the front lines with couples, I have grown increasingly aware that women have no corner on the low libido market. In fact, based on my clinical observations and casual conversations with colleagues, I’d say that low desire in men is America’s best kept secret. After all, in a culture where virility is inextricably connected with masculinity, why would any man want to broadcast his drop in desire? Most of the data available on the incidence of low libido in men is based on self-report and estimates vary widely. Do we really know what goes on behind bedroom doors? I don’t think so.
