Energy orgasms will clear the body of repressed emotions, old hurts, and blocks. They put a bounce in your step. Energy orgasms help pre-orgasmic women to become genitally orgasmic and help genitally orgasmic women to become much more multi-orgasmic ("megagasmic"), plus they make partner sex more ecstatic and fulfilling. It's safe sex, a good substitute for harmful addictions, and a great party trick! Energy orgasms can be an extremely spiritual experience, giving you a sense of the forces of creation rushing through you, a sense of going beyond the body/mind, reminding you who you are beyond your everyday reality.--Tantra.com
As Annie says, the energy orgasm technique is based on the Fire Breath Orgasm, taught by Harley Swiftdeer of the Deer Tribe. I personally take with a grain of salt Harley Swiftdeers's claim that the Cherokees would do fire breath orgasm in their ceremonies and that it was an important part of sex education and healing, but it doesn't really matter since the technique works.
