Sorry to hear about your struggles.
I am also a sex addict in recovery, my main acting out behaviours were online cybersex, excessive masturbation, watching pornography, and I also had a small number of anonymous sexual encounters.
It’s great that you’ve been going to therapy, but if you’ve been going for two years and don’t feel like you’ve made much progress, perhaps it would be worth looking into a different therapist? I’m on my second therapist, after the first one wasn’t working for me. I think it’s really important to find a therapist who is educated in, and really understands, sex addiction.
Another option could be SAA. I started going to a local SAA group around 3 months into my sobriety, and found it very helpful. I didn’t start on the steps for almost 9 months, which was a bit silly, but even just going along to the meetings once a week I found to be really beneficial. I’m now working through the steps with the help of a sponsor.
There are also sex addiction threads on here that will help to connect you to other sex addicts:
