Rage, anger and sexual compulsion are all tied together for me too (as well as others). There is a book titled "Lust, Anger, Love" and here is a blurb from Amazon:
"Canning shows how compulsions are the product of early childhood abuse and how patterns, from the most violent to the most commonplace, develop. She explains that the overriding emotion sexually addicted people feel towards the partners with whom they seek intimacy is anger turned into sexuality, or "sexualized anger." This yields a false sense of security and power, an "aggressive tendency," which destroys any chance of a healthy relationship. Lust, Anger, Love offers a comprehensive and enlightening look at the origins of these little discussed behaviors and maps out a plan for recovery."
I'm not advocating this book - just using it to make a point that anger and sexuality can be intertwined and it has been noticed by professionals in the field of sex addiction.
I doing a lot of work in this area of my life around my "medication" and letting go of it is bringing up real anger and aggression but by writing about it and talking about it, I am finally seeing what is underneath.
I so identified with wanting to keep that rageful person from taking over.
And more, much more, the heart may feel,
Than the pen may write or the lip reveal.
