Power Circuits: Polyamory In a Power Dynamic [EPUB ebook] 

Power Circuits is an alliance between two alternative lifestyles: polyamory, or multiple open and honest romantic relationships; and power dynamics, relationships that choose to be consciously and deliberately unequal in power, such as dominant/submissive or master/slave. Both lifestyles are on the cutting-edge frontiers of romantic and sexual relating, and for a long time practitioners of both have found little sympathy in either camp. This is the first book of its kind that navigates the waters of effective polyamory and power exchanges, with many essays from the brave practitioners who swim there.
