This is a thought provoking subject. I have noticed I seem to attract a lot of men with hard Mars to Pluto hard aspects. I never thought about just sexual abuse with these aspects, I usually look for any kind of abuse with either Mars, Uranus, or Pluto placed in the 4th or 12th houses, or the ruler of these houses in hard aspect to Mrs, Ur, and Pl. That will usually point to some sort of abuse in childhood. Besides any kind of abuse, Mars to Pluto or Mars to Uranus can also point to bad tempers and people who can be cruel at times. A great way to work with this energy is contact sports, therefore many professional athletes have Mars in hard aspect to Ur or Pluto.
My mother has a horrible temper and I believe(now)she is slightly bipolar. She was sexually abused as a child by her stepfather. She has Moon in hard aspect to Uranus(can point to bipolar) with Mars ruling her 4th house opposing Pluto(sexual abuse and bad temper). He was the only grandfather I knew btw, and my mom would send me to visit my grandparents!! Nothing like sending a lamb into the lion's den!! Thankfully, my grandfather never touched me but I always got a weird creeped out feeling whenever he would rub my back.
My mom was extremely critical of me as a child. She never really hit me though but her screaming voice could stop traffic. My best girlfriends father touched me inappropriately(actually once grabbed me and kissed me passionately - ewe!!!) a couple times until I stopped spending the night over there, and my stepfather was an exhibitionist with me. I would have to walk by their room to get to my bedroom and he would be naked in front of me with the door open but of course when my mom was there the he would close the door. My 12th is ruled by Aquarius and Jupiter is placed inside in Pisces opposing Uranus and Pluto in the 6th. Hum, I never thought about these aspects pointing to my sexual abuse!! I always sort of concentrated on my 4th house, with it being ruled by Cancer with Moon in Cancer placed inside and part of a natal Kite with Jupiter, Neptune and Pluto! This should offer a lot of protection, however my Moon is in a pitted degree so I believe this negates much of the good of the Kite configuration. Kind of an aha moment here!!
