It has slowed down, but I don't see that as a bad thing. My sex drive was horrible when I was a teenager and in my early 20's. Hard all the time. At some point it was annoying, and a distraction, even more so when I was single. I had inconvenient things like work that kept me from jerking off all day.
the orgasms are much more intense much more satisying and longer than they were when i was younger. Things seem to get better as we age. Sex is better than ever! Wow who would have thought it could be any better?
50 and horny as hell!
