Yes, my views on porn have changed radically. I initially started using it as a way to escape the drudgery of caring for my baby, but became more and more disturbed by the violence, abuse and degradation. I would find myself looking at the young women in the videos and wondering who they were, and what kind of adversity had caused them to end up in porn. And yet, even though I knew it was wrong, I carried in using it, because I felt I needed that escapism so badly (I also had PND).
Finally, the cognitive dissonance became overwhelming. I was volunteering for a charity that supported CSA survivors. One night I came home, went on pornhub and was scrolling past the ubiquitous incest-themed videos, and it struck me that I was part of the problem. Ok, so I didn't watch these nonce-orientated videos, but to repeatedly visit a site that hosted such content was to tacitly participate in the normalisation of paedophilia.
That was seven years ago, and I haven't watched porn since. However, I'm definitely still a work in progress. E.g. I'm a radical feminist now and opposed to BDSM, but there are aspects of my sexual programming I'll probably never be able to undo, and I'm ok with that. I'm not going to crucify myself for enjoying a bit of rough sex now and then.
Please be kind to yourself also. It takes courage and integrity to confront such things. You should be proud of yourself. Remember, you were raised in possibly the most pornified culture that has ever existed: that's not your fault. You've made an effort to explore the realities of the porn industry, which is something that most people will never do. Now you know better, you'll do better.
Enjoy this time with your baby and don't feel guilty for things that are not your fault. Are you receiving support and treatment for the PND?
