I wonder if a provider's age/experience has any bearing on service provided. Being a bit older than the group, I am skeptical that a 21-25 year old can deliver what a 31-35 year old can, especially in the world of sensual domination.  Am I all wet here... is this bias making me miss out on some great experiences?

...that age can be a reflection of one's experience, since time, effort, and study all make up the end result. Having said that, there are exceptions to every rule. The specialties that one seeks can also level the playing field.

I would agree & recommend a well rounded provider in her 30's who has been playing for several years because you would hate to be bias to, then pick an older lady who still has no clue what Sensual Domination is.

Unless the young player is a life-style she is more, than likely looking to make more $ in the adult industry by faking it until she makes it, so you pay her to practice, which is unacceptable.  The unexperienced should be honest & offer specials to acquire skills.

Thnx. Maybe the ticket is a young lady in need of tutoring, and 30s lady willing to tutor... with me in between. Any like that in DC?

...in a way that I find very comfortable.  I've dated a lot of powerful men who had a desire for a safe place where they could just let go of responsibility and know it would be all good, and providing that place has transitioned into my business life, as I see the same types of clients.  It's an attitude, and tho some have dominant folks been dabbling with BDSM since they were teenagers, my curiosity has been born of experience and maturity.
