Sorry, it's been awhile since I have followed up on anything...Here is the quote from a previous thread about the astrology of BDSM and Aries in particular
DOMINANT ARIES
Aries is a naturally dominant sign, in many ways. The aries tends to be hard-headed and spirited, and is dissatisfied when things are not done his way. He will hold his slave to high personal standards, and will demand things be done to his liking above all else. He can be confrontational and protective, and is intensely passionate, so his slave will be well-looked after.
SUBMISSIVE ARIES
Most people know that gemini and pisces are dual signs (as are many others), but few know that aries is as well. Aries is the ram, but also the sheep. Submissive aries will retain the fire and passion of the dominant, but he will shy from confrontation, and serve obediently. Nevertheless, this slave epitomizes the truism that bondage is really all about the bottom, because without attention and devotion, the aries slave will become easily upset and rebellious.
