Are there any providers out there that accept to see young guys (age 20) instead of the older gentlemen crowd.

As long as you have a good reference, I'll see ya. I've seen men younger than me and sometimes they are just as gentleman like as the older gentlemen. I could be your cougar.....

As long as you have a reference and can be verified, I always enjoy the company of younger guys.  My suggestion is just contact whomever it is you are interested in.

Good luck & have fun!
