Not wanting your partner to watch porn is okay and doesn’t make you an insecure person. It is a boundary that is okay to have.

This is true... But labeling someone as an addict just because they aren't willing to place you above it isn't exactly promoting an honest dialog on the subject either.

Thus far the only information provided is that he likes porn. Not that he's spanking his monkey non-stop or into some extreme deviant shit... He just watches porn and we're labeling him as an addict exclusively because he likes it at least as much as he likes his current gf who we know nothing about.

That isn't how addiction is defined or diagnosed and labeling everyone who watches porn as an addict is a hyper-reactionary modern take that really needs to die since it trivializes those who actually have a porn addiction.
