from personal experience, it is my belief that indulging in pornography and fantasy has only hindered my healing process.
at first, i thought it was a "safe" and "harmless" way of calming compulsive thoughts. but it has had a deep negative impact on my life. nothing good came of it. that path is a one-way street on a dead-end road. pornography and fantasy became a barrier between me and my partner, and more importantly, it came between me and my creator.
i recommend the bible. read it. study it. discuss it.
and for the sake of your own soul... learn to love and forgive those who abused you.
BUT FIRST... love and forgive YOURSELF!
you will find the compulsive thoughts will diminish, and dissipate... gradually, but certainly.
hope it works for you as it has worked for me.
