I don't want to summarize everything which is written in this book, but this video tries at least partly: https://www.youtube.com/watch?v=e2mhQf8RjQs

Now here's the thing which completely blew my mind and why i stopped:

- Porn changes your view of sex to such a specific point that you're having erectile dysfunctions while trying to mate with a real person. (this happens because your brain is getting way more stimulation by porn then by your girl and got used to it)

- porn messes with the rewards center in your brain. you perceive all the things we are trying to achieve like: friendship, career, relationship, hobbies, self-improvement goals as less rewarding.

there are other side effects like reducing depression, social anxiety and others when quitting porn.

how are your experiences after you quit?
