I just think continue to do your utmost to never act out on your zoophilia thoughts/urges, which is what you are doing. And maybe meditation can help you with learning to let go/diminish the attachment to these thoughts. Me, I get negative urges of a different kind in my head which over time are diminishing loosing their power and frequency. It's good. I've made a lot of lifestyle changes over years but I do believe mindfulness meditation (you can Google that) and ordinary meditation, especially during rough times, have helped. Just commit yourself in whatever ways you like, to healthier lifestyle. No harming things.🙏
