Beyond Tantra: the Yugmapad-Asana TechniqueSocial Networking & Dating
Key to this method is the acquisition of a round, often cowhide cushion known as a zafu.
Generally about 18--24 inches in diameter, this cushion must be large enough for the man to be able to sit comfortably on its edge without slipping off--but not much larger. Commonly, the technique begins with the man sitting naked on the edge of the cushion while the woman sits naked before him, stimulating his penis to full erection. (If the women knows the little tricks the man especially enjoys to become aroused, she should use them so as to achieve the hardest erection possible.) Once completely hard, the man should sit on the very edge of the zafu, lift himself slightly off the cushion, and slip his right foot under his buttocks so that the heel is positioned behind his scrotum, slightly to the right in what is known as the "perineum," (the space between the penis shaft and the anus). He should then lower his weight onto his heel, feeling it press into this soft spot (as if sitting on a tennis ball). If positioned properly, the man will feel a rather pleasant sensation traveling up his anus as if his prostrate is being gently manipulated. The idea is to apply pressure to a particular muscle and pair of glands that control blood and semen flow to the penis. Once positioned comfortably, the man should then lean back on his extended arms, shift his upper body weigh backward, and lets his organ extend itself. (This will be visual and apparent and should serve to excite the woman as well.) Within a minute or two the penis will engorge and lengthen to its maximum length--typically an inch to an inch and a half longer than normal. Then the woman can simply climb on--either straddling his erection, sit in a kneeling position, or by wrapping her legs around his waist.
He will be in a perfect position to thrust into her, or he can let her ride him to climax. I have personally used this method for many years and can attest to its effectiveness--and the amazing sexually-pleasing fulfillment it can achieve. Note: if you are unable to achieve this method the very first time, do not be discouraged. This is a technique that requires both partners to concentrate their efforts, and may take a few attempts to coordinate. But once you do . . .
