Being a more younger and inexperienced lover myself is that usually a bigger turn off for providers? Or do providers usually prefer the more experienced type so they can be more pleased with the overall experience?

Older gents are often grateful for the company of a younger woman.  I younger man may may be more critical of paying for anything less then perfection.

Attitude is the biggest issue.  Women generally want to be respected and treated kindly and gently.  Older men seem to understand that more.

You do not have to be a good lover but it doesn't hurt.  This may be an opportunity to learn from an experienced woman if you ask her to teach you.

An older provider may be a better teacher and a better lover then that hot 20 something chick.

A provider I most often recommend to friends is in her 40s and is an awesome passionate lover. (See my review of Vivienne)

not interested in anyone younger than 40, many women in this business feel this way, but not all.
everything improves in time and with experience so does a lover so i see only Gentlemen who have experience of time as well as usually long term relationships.
Its all preferences.

Providers prefer to be paid. Beyond that being prompt, courteous and clean all rank very high on their lists.  Some ladies do prefer to see older gentlemen and will state this on their web sites or in their ads but this has more to do with maturity than sexual experience.

Wow, Vivienne looks MONDO exotic.

I love all men!  BUT I do prefer men older than 35 in this hobby.  It's a respect thing and older men have that.  Not to say all younger men are disrespectful, but they do seem to carry that "attitude" as said before.  Also experience in the hobby itself... an older man has been there before, may have been married, and knows how to treat a provider.  I think sometimes a younger man just takes it for granted.  Just my 3 cents....
