Have you asked your wife how *she* feels about this? I'm 39 also, with a 42-year-old girlfriend who can (and happily does) screw me into a stupor several times in a day.
I *don't* see this as a problem at all.
Just think of it as good sweaty fun noisy exercise that will extend your life- very extropian indeed. What you probably need is better sex, not less ;)
As for not siring more kids, just get a vasectomy as I did a little while ago- just keep the icepacks on there for a few days and you'll do fine...
