Have you reached a point of sexual non-interest? At what age did you reach this point? Do you miss the sexual contact?
My sex drive runs in peaks and valleys, and the older I get the more extended the valleys get and the fewer the peaks. The good news (at least for me) is that the peaks are, if possible, even more insistent now than when I was in my early 30s. For any number of reasons, including the sexualized nature of my job, I've been in a valley since mid-summer. I still JO, but not as often, nor with the same urgency: I'm just totally not in the mood these days.
Like Bbucko, I also have peaks and valleys. Due to recent surgery I am in menopause, so I expect these peaks and valleys will get more intense.
