Tantra is a keyword that seems to have the best potential here.

Many providers who offer a sensual massage really mean they offer a massage with a hr finish.  Sometimes it's sensual, usually it's mechanical.

Some Tantra providers do this, and some do the whole breathing thing, but a few give a really sensual massage that is just short of sex.

Veronica, of Atlanta, who comes to NY is phenomenal.  I hear her friend Merry offers similar quality, but haven't had the experience myself yet.  They are both fairly expensive, though.  

There is someone else in Midtown who might be good for this as well.  Planning on seeing this week.  Will report back...

I sent her an email because I'd like to schedule a massage too, but haven't heard back...
