Is there a rule of thumb for Providers and Clients? I know there are fetishes, but do Providers use a 10 year rule?
There are some providers won't see guys under a certain age. I think that kind of restriction is because she doesn't want some young guy pounding away for the whole hour. . Being in the target demographic, i.e. over 40 (okay, well over 40) I've never had a provider tell me I was the wrong age for her. There may be some that set a max age also (Tobi Telford?) But it's rare.
I will not see clients under 35 and I have stuck with that rule since starting. I still get alot of request from guys asking me to make an exception but I do not. I have more in common with clients that are older then me. So for me it is not all about making money because if I lowered my age requirement I would make alot more money.
Also over 40...and white. I'm surprised they aren't lined up outside my door somedays!
....RARELY honest about their age, anyway LOL! Of course, there are exceptions, but I've met several over the past few years that are shamelessly dishonest about their true age.
They just age differently than the rest of us, after they turn 18. Some age by 1 once every 2 to 3 years, some can stop time for about 5 years. I have seen others age only by 1 for ten years! Our providers are equal to God when it comes to how they can control time.
Ohh also, their hour is generally 50 minutes instead of the 60 minutes. It is just that their time is different from the rest of us!..
...a note from his mommy. 
Don't worry about it. It's rare for a lady to have an upper age limit and they'll likely say so in their ads or website if they do. Many ladies, whether young or mature, advertise they prefer men over 40 with no upper age limit.
Love i$ a beautiful thing... 
suppose everyone is familiar with the Scottsdale City Ordinance, Sec. 16-471. - Prohibited activities.
(a)
It shall be unlawful for a permit holder to provide an escort to individuals under eighteen (18) years of age unless written and notarized authorization by a parent or legal guardian is given to the escort before the services are rendered
$ is the great equalizer my friend.
It was a loaded question and was hoping to get more local Provider feedback. I'm only 43, but wanted to see how the board would react if I posted an age question.
The Hobbyists' were inspirational though...LOL..If I ever make it to 80 years old and have an erection lasting longer then 4 hours.....The pics would make it to Facebook...I would be proud.....
