Thank you for the thoughtful feedback!
I myself have actually gone back and forth over whether sex addiction and porn addiction are real. It was only after going through my certification course and having to find research to back my position that I realized how little support there was for the concepts and how tied to sexual shame efforts like 'no fap' are.
I truly feel for people who believe masturbation is ruining their life, and can't deny that some levels of masturbation can affect genital sensation, erection, and orgasm. My hope is this piece compassionately reaches those people and encourages them to take a deep breath and decide to work on their masturbation habits without shame.
