I suppose, it's existence is not dependent on your or my beliefs. What exactly IS "sex magic"? Is sex ALWAYS magic even when we don't intentionally desire any conjuring?

Every civilization has a complex set of rules that limit individual sexual behavior. Violators are labeled as deviants and they suffer social disapproval. The limitations serve to restrict the exploration and practice of sex magic.

I think "sex" is a conduit of strong cosmic energy and this energy CAN be intentionally manipulated through skillful channeling. I also believe we can benefit from this energy flow without fully understanding all the nuances of directing this energy traffic. The corollary of course is that we can also suffer undesirable consequences as a result of it's unfortunate misdirection - all without the requirement for knowing or even believing.

Let's assume "sex magic" is real - and by that, I mean it is possible to observe PREDICTABLE RESULTS for which we have no other reasonable explanation. We perceive a cause and effect relationship between specific sexual activity and "curious results". Let's also assume almost any participant(s) can invoke low levels of this magic by following a "recipe" (ritual) without a requirement for specific mystical training or unique personal characteristics.

Let's explore "swinging sex" from this perspective. The predictable curious result is a special closeness within the marital relationship (it may be difficult to put into words, but we all recognize it in ourselves and others) - a love spell we cast upon ourselves collectively. The ritual is a simple drama free sex party of mature experienced swinger couples. No need to recite magic spells, charm a circle or summon elementals for protection. No one gets hurt, abused or disrespected. Everyone enthusiastically participates of their own volition and is satisfied at the conclusion of the ritual. The interesting feature of this simple magic is that it is all internal to the participants. We're not casting love spells on innocent bystanders (psionic rape) nor divining next week's lottery numbers (predatory greed).

The swingers party ritual is simple and there are many variants on the theme which are likely to produce similar results and as we all know, there are other variants where people get their feelings hurt that tend to invoke some undesirable results or reduce the magnitude of the desirable results. The spell normally has a reasonable durability and the need for it to be refreshed will vary among the participants. What more could you want from some simple low level magic that doesn't require years of special preparation or consume special magic components?

I believe Karezza is another magic sexual ritual, but that's another chapter.....
