I prefer the latter, I think the experience gets better with more and more visits as she gets to know me better.  The first time with a new provider is always awkward for me anyway...

I have little choice.

I do like to get to know the ladies, yet do to an agreement I made I can't visit a lady more then once every two months and for no longer then 2 hours.

So while I am sure I would prefer "the variety seeing the same person but discovering new experiences each time out", but because of the rule I must follow I get the "variety of seeing someone new and having a whole new experience" most often.

I wise escort ehhorted me to see at least six new gals a years, and I have endeavored to do just that for the past six years now.

That combined with seeing regulars keeps a nice balance.
