I'm a guy who is not addicted to porn, though i can't say what is clinically considered an addiction. I would say that if he prefers looking at porn on a computer screen, as opposed to the real thing, if you know what i mean, he might be addicted. Maybe you could discuss this with your therapist and see if he/she has a solution. If the problem persists and is degrading your mental health i would say find a new guy. I know I prefer the real thing.
