While Christianity had traditionally frowned upon public references to sex and upon any attempts to treasure what it still sees as a fundamentally dirty and degrading act, other religions and peoples had different ideas. The best known of the exotic systems of beliefs are Tantra and various pagan denominations. Among the lesser-known systems are the beliefs of certain tribes from Papua New Guinea and Africa.
The basic idea behind such beliefs is that semen is a fluid with magic properties that can be used to augment the natural powers of other people. Some pagan circles say that semen contains the power of the male, which can be transferred to female priestesses through sex. Certain rituals include the copulation between a priestess and two or more males in order to “harvest” their semen and increase her powers.
Tantra is an esoteric tradition rooted in the religions of India, a body of beliefs and practices that differ somewhat from sect to sect, although all the sects tend to adhere to the overarching belief that the material universe is the concrete manifestation of divine energy. Some Tantra rituals include sex, but the reputation of religion of sex Tantra has in Europe or America is absurd.
Semen as a magic fluid was also a key component in many occult theories and practices in Europe and America. Occult figures like Aleister Crowley and Samael Aun Weor spoke about the power of sex and its significance in a magic context. Likewise, semen was thought to be a source of power and one of the fashions that set the occult world of fire last century was that men should never ejaculate in order to activate and increase their power.
