Because with true Tantra, there are no goals. It takes time (HOURS!) to create the connection necessary to have an enlightening experience. That's not to say that there isn't sexy time, too, with some practitioners BUT it's not like a traditional escort experience where you have a menu of acronyms, if that makes sense.
The vibe is very mellow, it's quiet, aside from breathing guidance, in my sessions anyway. It's all about the connection, especially with yourself. Most guys assume Tantra basically means just one awesome orgasm, which isn't the case at all. You may have multiple orgasms without a release. Of course, most of my guys want that, so I am happy, no pun intended, to oblige because it really *does* feel good. Personally, I prefer a light massage and then, Yoni massage over just receiving traditional oral which to me, is underwhelming. LOL Tantra also helps those with erectile dysfunction because there aren't any goals, no pressure to perform.
As far as rates are concerned, mine are higher as are my time minimums. Why? Because there is a lot of preparation involved. Depending on the length of our session, I may start to prepare energetically a day or two before, eating habits change so that energy is not effected, the actual supplies are top notch. The oil blends used are all handmade, there is the time spent for schooling (LMT), the spiritual practice of Tantra is a lifestyle, not just for our appointment. Plus, there are other esoteric or metaphysical gifts, that aren't duplicatable.
I'm curious why you were underwhelmed? How long of a session did you book
