I thought this topic was stupid so I wasn't really sure why I came into this thread again, but a lurker has always been so insightful and I just love reading the comments going back and forth here.
I think it's great that anyone that has had sex is automatically sex crazed because it feels good. Just like drinking alcohol, I loved my first buzz, I think I'll go be an alcoholic now because my body craves it. The whole sex drive thing has nothing to do with any of this. We all have out of control sex drives according to what's been said.
Anyway, back to the original topic, you're never too old for anything would be my answer.
Jam it back in, in the dark.
