A major tenet in Tantric beliefs is the importance of ejaculation mastery. Many ancient gurus believed ejaculation was a waste of vital life energy, so men were taught to condition themselves to preserve their seminal fluid and to release it as infrequently as possible. This was because of the great drain on physical energy and vital force when a man ejaculates. It was also believed that men should instead use that energy as fuel for awakening the higher chakra centers and thus to move on to enlightenment.
As a result, traditional Tantric men became experts at controlling (and avoiding) ejaculation. Sometimes this involved considerable effort or complicated processes. One Tantric text describes a specific elaborate pattern of strokes of movements that, if the man followed them exactly, were said to prevent him from reaching a level of excitement that would allow ejaculation to occur. Other techniques were extremely simple, such as pressing the tongue against the roof of the mouth.
Men would also delay orgasm in order to prolong the sexual union until they were certain they had pleased their goddess (satisfied their female partner). It was also commonly believed that keeping his penis inside the woman for as long as possible without ejaculating enabled the man to absorb some of the woman's vital life juices and powerful energy.
Today, there is some division on the importance of ejaculation (or avoidance of ejaculation). Some still believe it is important to completely avoid ejaculation, while others disagree. Men understand that they are not going to “run out” of seminal fluid. However, it is still considered important to delay the orgasm as long as possible, in order to allow for a long, satisfying sexual encounter.
The easiest and most common way to avoid ejaculation is simply the start-and-stop technique. Just like it sounds, with this technique the man participates in sex as usual, until he gets to the point where he feels he is about to ejaculate. He then stops completely, and perhaps even squeezes or puts pressure on his penis to help the urge to ejaculate subside a bit. Once the urge to ejaculate has receded somewhat, the man can then proceed with the lovemaking process. He can continue with this start/stop pattern until he is ready to ejaculate (or if it becomes uncomfortable), at which point he should allow himself the release.
Other techniques that are said to sometimes help in delaying a man's orgasm include pressing on the perineum (spot between scrotum and anus) or pulling gently on the testicle right before orgasm is about to occur. Both of these techniques should be performed carefully and gently, to avoid pain or injury.
