Tantric massage is one of the most underrated skills in the business. Once upon a time I had an MPA who provided the best of the best tantric service. Essentially, it's the art of gradual stimulation to the point of...well you know....and then being hung there for as long as 15 minutes. So you right at the edge of finishing and they old back. To the edge and back. When it happens it is unlike any other experience. Really, really good.
The problem is that with so many MP's around, the business has become almost like factories. Get you in, get you off and get you out. For example a good tantric experience will take at least an hour. Most MP's in the vein above encourage the half hour because most of their money comes in the tip.
I've only ever had it don't by Asians. One was actually quite old but knew what to do. The best one I knew left the business and I have one MPA that I've been seeing for years that is still one of the best. I remember there were places that advertised tantra experiences. They always sounded expensive and I've never tried them. Would be interesting to hear from those who have.
