Porn addiction destroys marriages. My STBX husband left me after denying sex addiction for 17 years of marriage. He has had emotional affairs, endless crushes, and flirts with women and gay men. He is sexually anorexic too and his penis is chaffed from frequent masturbation. I think he underlying disorders like BPD / NPD. He is verbally and emotionally abuses and blames me for the craziest things...like him falling for other women, stealing his happiness, etc.

I can't believe he left me although the porn / weird sex has been an issue since we were teens. Sex addiction is a major red flag.

Do not ignore it. It's the tip of the iceburg.
