Passion, Passion, and I love to get the lady to cum. It is just important to me for me to make her have that "O". That is the first thing for me. Being an old fart, sometimes, I take too long, but as long as I get her off, that makes my date.
Good point Cajunman.....the most wonderful and sensual moment is to experience a passionate real female orgasm....very hard to find....but always very beautiful when you find them!!!!!
I think it is just the sheer animal lust of the situation. The providers I have seen are just so hot and as a hobbyist if you can work it so the provider you are with enjoys herself so much that she is in the sheer animal lust of the moment as well; it just makes it for a wild session. I think that is the best thing about the hobby; nothing but just HOT, WILD SEX
