Hi Patagonia: I seem to recall having read that women reach their sexual peak in their 40's. (I could be wrong about that.) But one thing I do know, from personal experience, is that men typically begin to slow down around that age. And, I'm sorry to report that (again based on my own experience) it's all downhill from there on out. I'm sure this isn't true of every man. But, for me, with all that's gone on, by the time I reached my late 50's & now into my 60's I have almost no sex drive left at all. And, personally I'm glad it's gone.
