There is a common misconception about Tantra that I would really like to dispel. Occasionally I hear people express a concern or reluctance to explore tantra because they have heard that during tantric sex, you are not allowed to cum. This misunderstanding naturally discourages people from wanting to explore Tantra because it sounds potentially frustrating and unsatisfying. Especially if you interpret this to mean you cannot have an orgasm. The good news is, this is not the case. Yes, there are some Tantric techniques that are taught and practiced among some tantrikas for enjoying sex without ejaculating. There is some real value in this practice, particularly in learning how to experience orgasms without ejaculating, because this opens up some interesting sexual possibilities. If this intrigues you, then I highly recommend giving it a try. However, these practices are not a mandatory part of Tantric sex.
Tantra is both a spiritual practice and sexual philosophy, yet it is not a religion or system that involves restrictions, denial or deprivation of any kind. In fact the practice of Tantra often encourages followers to explore and dispel taboos. Tantra is a practice of consciously saying yes to life and yes to new experiences. There really are no rules against anything pleasurable or mutually consensual in Tantra, especially no rules forbidding orgasms or even ejaculating. Tantra is practiced across many cultures, and in conjunction with various religious and cultural beliefs that sometimes get mixed up with the pure practice of Tantra. Sex without any ejaculation at all is a practice that I believe stems from a cultural / spiritual belief that is not purely tantric in origin, but rather a philosophy of longevity that is practiced by some Hindus and Taoists. There is a belief that preserving the ejaculation fluid inside your body preserves your life force energy and therefore prolongs your life. However, this is not a belief held or practiced by all Tantric lovers around the world. The majority of American and European Tantric lovers that I know do not feel compelled to practice a strict form of non-ejaculation with tantric sex. However, prolonging arousal or postponing climax to allow the energy to reach a higher level is often practiced as a way to expand awareness and orgasmic bliss.
The art of prolonging pleasure without reaching climax is described in the Kama Sutra, the Hindu sex manual written in the 4th century. "Karezza" is the term used to define a practice of the male pleasuring his partner and prolonging their intercourse by perpetuating his state of orgasm without actually ejaculating. With practice, he may experience a sensation of internal and sometimes multiple internal orgasms. Some people refer to this type of orgasm as a dry orgasm because it happens without ejaculation. A dry orgasm is pleasurable, yet still allows the sexual act to continue, prolonging the state of orgasmic bliss for a couple's mutual enjoyment. The art of Karezza incorporates breath control, meditation, work with postures, and finger pressure into the sexual act.
