Sounds very interesting, but I can not quite fathom how exactly an "intellectual orgasm" would feel like or be triggered. could you please explain the difference between an intellectual orgasm, and a dry orgasm?

I know some adepts of various occult taoism and hinduism describe what are called "crown center orgasms" which are felt specifically in the head!!!

you should check it out, as it sounds similar to what you are speaking of.
