Great answers and what a variety of age ranges!

I did not ask the question as an insult to "old people," but more along the lines of trying to figure out if a T that practiced with "crazy people like me" for along time, would be burned out and have less patience if they were older and still practicing.

My last T was close to me in age and it was horrible. So, I wanted to try someone older...but then how old is too old before T's get tired..you know?
