I guess define young - I would say the majority of "established" providers are in the 30+ range - plenty in their 40's+.

There are new providers coming into (and out of) the market all the time at various ages - I would say there is a "new" market caused by advertising sources of younger girls.

I see Vegas and Dallas as younger provider markets than Phoenix. Chicago perhaps a bit more mature. Used to hobby there years ago.

As for mature providers -  "GOT SKILLS" - is the name of the game... your references (reviews, folks you know, look, etc) are as important as guys truth be told (do not know you - general comment).

It does seem younger providers touring through get more "action" - but what do I know.

This is not a young market.

As I get older, like a fine wine I only get better with time.  I started providing in college at age 21, and now in my dirty thirties I find younger guys & older appreciate a reputable provider regardless of age.  Never assume.  I have a friend who is almost 60 & she out does all the young girlies when traveling.  Everyone loves a MILF, but a GILF even better.  Experience is our greatest teacher.  If you, like high end hotels I prefer the Princess in Scottsdale.
