Sex Magick
Sex: (noun) from Latin sexus "a sex, state of being either male or female, gender,"                                     ___________________________________________ 
   Sex magick is quite simply any type of sexual activity used in magical, ritualistic or otherwise religious and spiritual pursuit. Sex magick techniques can be used in any operation. One practice of sex magic is using the energy of sexual arousal or orgasm with visualization of a desired result. The particular symbolism and mechanics of sex make it most suitable for works involving union of opposites, creation, and transformation. Any successful magical operation creates a "magical child" on some plane, but this effect is especially strong in sexual operations. Obviously, one potential plane on which such a child can appear is the material plane, if conception occur.
     Sex magicians such as Austin Osman Spare, openly advocate the use of the sex act -- or the passions or arousal states it evokes -- as a point upon which to focus their wills or magical desire for effects in the non-sexual world. This is fine and well, but for some reason, many of these same sex magicians also seem to feel that tantrikas and karezza folks lack a similar interest in using the sex act as a focal point for will. For instance, in 1995 there was some discussion in usenet of whether tantra is simply a "spiritual" path and thus not suitable to be listed among the "magical" disciplines archived by tyagi nagasiva (who maintains a valuable reference file on accessing information on the occult via the net.
     The split between "spiritual sex" and "magical sex" does not lie on the line that divides tantra and karezza from sex magic -- it lies on the line that divides certain forms of tantra from other forms of tantra and all karezza.  For instance, in the 1870's Paschal  Beverly  Randolph,  an  American  author
   

whom many sex-magicians consider one of themselves, wrote (in his book "Eulis!") of using the "nuptive moment" (orgasm) as the time to make a "prayer" (and that is the word he used) for events to occur as well as for healthy offspring to follow. Likewise, Bunker Stockham, the proponent of techniques (and not a sex-magician) wrote of using the act of coition as a time to pray for non-sexual goals in the outer world, such as "charity." Similarly, in traditional Hindu tantra, the yoni puja ceremony (performed either upon the vulva of a living woman or upon a stone statue of a woman's genitals) is often accompanied by prayers for effects in the real world -- magical (a-causal) effects such as a better job, restored health, and so forth.
I     n short, it is likely that many sex-magicians are ignorant of the use of the will in tantra and karezza. Which is to say that the distinction some sex magicians see between sex-magic and sex-religion is based in ignorance on their part.
