I'm a bit older than you and have seen maybe *** providers over the past three-plus decades. Age has never been any kind of problem, except with a very few of the youngest most shallow bikini bozettes from LA and Florida. The very young and exceptionally pretty tend to be so vain & empty that they are miserable providers for everyone.
In your shoes, I would go with maybe 23 and older only, most of whom can put together a compound sentence. There are certainly exceptions up and down. Do several hours of TER Review research in your cities, and you'll be surprised how many ladies fit the pickiest of profiles. Most of the Ripoffs are the young bikini hotties though.

Give us a preferred vix profile & metro area, and several TER priests will pass along information about ladies whose companionship is very fine. If you use enough Viagra you can enjoy three per day.

(not a provider)

This has been asked several times before, and the response from the ladies has been that:
It doesn't matter if the guy is young, old, fat, thin or neon green.
If he's clean and treats her like a lady, then a good time will be had by all.

(of course, some ladies might be a little put off by the neon green fellows out there)
