Yes. Some are addicted to sex/porn/etc. , others substances, and some like to eat couches. All can be detrimental to the individual and others around them, and therein lies the issue. In my opinion, if it doesn't affect anyone negatively, it's no one's business except for the person partaking.

Addiction is addiction. If it's affecting you or others lives negatively, it's an issue. It doesn't matter what one is addicted to.

Everyone deserves a chance to be happy without unhealthy temporary fixes to cope with their existence.
