Here's two techniques and some info.
When the military held their "Don't Ask, Don't Tell" hearings, one of the grim sidebars was regarding the tendency of homosexual sex offenders to have "serial" behavior. This horrific pattern is one reason the stats for male child molestation are so high when the homosexual populace is so low. As you know, many sexual predators were themselves preyed upon, and they try to relive the power play, now casting themselves as the "winner." I hope you will help to lobby for more rigid control of sex offenders, especially in light of recent cases.
I do commend two means of resolving the trauma. One is a quirky Meridian Point therapy called E.F.T. It works on vets with Post-Traumatic Stress Syndrome so carry on even though this is idiosyncratic. It works. I believe it removes the "chemical signature" that is left after trauma, which hinders healing.
And I also have high regard for Roy Master's "de-hypnotism" meditation, his "Observation Meditation. Trauma, which can be pleasure or pain, creates a kind of hypnotic suggestion. Master's Meditation brings subconscious messages out on the "mind's eye" readout. When brought to light, they melt away. Master's works with a lot of sexual assault victims. I would consider contacting his Foundation of Human Understanding.

Both have free intro's. Here's the websites for both and I hope you take advantage of these powerful techniques. God bless you and yours, and I pray we can short-circuit the cycle of abuse so this predation is attenuated if not eliminated.
