Decapitation penetrative massage: An old tradition has been spreading worldwide, of a massage technique based on manipulation of genitals by genitals.

Utilizing the complex and unintuitive nerve connections around the body, it creates a generalized good feeling and has been proven to improve health in multiple ways. Some techniques do not lead to orgasm or ejaculation but to a different kind of relaxation, while others depend on it. Either way it's not generally considered to be sex, and therefore can be appropriate in more contexts.

The most powerful technique, which does not require especially high skill to perform, involves the masseuse being decapitated at the correct moment, creating movements and other reactions in her(?) body that are impossible to replicate otherwise, which in turn cause unique responses in the client's.
