As the saying goes, 15 will get you 20...
Personally, I would prefer the company of an experienced woman as opposed to a fumbling newcomer. My sexual tastes almost demand someone with experience. There is a whole big world of sexual variation out there, be it positions, toys, fetishes, etc. that are seen as lewd by some, but those same people I have seen shelling out large sums of dollar bills at the local Gentleman's Club. Those dancers know as well that everyone has a fetish, and in their case, it's lucrative.
In closing, your fetish is yours to have, but I agree with Dark Master Prince. A legal 18 year old that has had time to gain some experience at least will be the better choice, and you won't have to worry about that pesky jail sentence.
