Regarding perversion - that's a question of intent and of course, you would have to speak for yourself on that. Regarding Orgasmic meditation - the un-initiated mind might see it as an excuse to get (his) hand on some pussy. The inquiring mind might wonder what this "sex positive" movement is really all about. Speaking from experience, it is a meditation, cultivating awareness, generating sexual energy, and then in the case of those with the appropriate intention - transmuting it into an abstracted form of creativity, empowerment and success.
