There is also a FAQ for my Journal at the same link.

"It may sound severe. Almost anti-erotic. Until you see two people, owner and owned, existing in a complementary relationship where each suits the other like balances on a delicate scale. Until you feel the energy of their rapport, you cannot understand how they fulfill each other, take and give in ways no negotiation could possibly express.

Then, you will understand that singular intimacy which drives such people on their search for perfection. It is beyond orgasm. Beyond love. It can almost be called rapture."
