I hated my vebally and emotonally abusive wife - PMO was my sanctuary

I can't say I've been in the same situation as you regarding a partner, but I can understand how being in a loveless and bitter relationship would make you want to seek out gratification elsewhere. The problem is with PMO, you often get what you want but sadly, not what you really need. Sounds to me like you were actually craving intimacy, connection and trust with another partner and porn became a very poor yet strangely satisfying substitute. A bit like knowing you need to lose weight and then eating junk food because you're hungry, it satisfies your hunger but you know it's not good for you. I hope you have a better relationship with your current GF

 

I've been in the same situation, minus the fatness (she actually had the body of an East European porn actress).

I reacted by playing more Stag Knight 2. Videogames are basically similar to porn however, and also activate the brain's reward centres.

 

Your specific experience might not be super-common, but your general experience is very common.

Not many guys deal with a girlfriend who's Borderline. But virtually every guy here knows what it's like to use PMO as an escape from uncomfortable situations or feelings. When you're doing something to medicate feelings instead of for the enjoyment of the thing itself, that's usually a good sign of addiction. Someone who drinks with friends because it's fun is less likely to become an alcoholic than someone who drinks because it numbs their pain.

The fact that you recognize the connection is a really great sign. And with 91 days, clearly the new GF isn't giving you the same grief. Way to go, man!
