I went on a no porn diet for a variety of reasons. I'm rational enough to accept that the notion that it might be affecting my relationships wasn't a completely nonexistent possibility. But, if nothing else, at least to give it a try and see what would happen out of curiosity. In the beginning it was difficult. But eventually I just got used to it. Let your gf know you're trying this out, but that you still need to crank one out on a daily basis (if you don't see her every day, or just need a quickie on occasion). And she can help you out by sending super sexy pictures. Maybe it's still technically porn, but it's her. And maybe she's the type that will get off on you jerking it to pictures of her.

I've been doing this for probably 10 months now. Jerking it either to nothing or to pictures of my gf. And my conclusion is that it's both good and bad.

The good part is the absence of a constant influx of porn-esque style girls has led me to not have fleeting desires for the traits of random porn-esque girls. I.e. subconsciously believing that porn-esque girls are real, as real as they are portrayed in the porn, available to me, and/or even something I would actually want. Whether admitted or not, the porn is affecting (to whatever degree) some aspect of the viewer's subconscious notion of a girl.

The bad part is that I think porn can satisfy the instinctual male desire (however big or small) for variety. So when you stop watching porn, you lose that variety, and your gf might seem a bit more ... "usual". The idea being that it takes experiencing something different from what you experience all the time ... to appreciate what you experience all the time. I think this is a common phenomenon in life. Eat filet mignon every day for a month ... "ugh, filet mignon again". Eat a salad every day for the next week, and by the end of the week ... "oh man, filet mignon sounds good right now". Obviously that has limits though. You can't be entirely selfish in life. You don't go off and bang a prostitute once a month to keep your personal variety in check. You're not the only one involved in your relationship, and involved in your sexuality.

Ultimately, I think it boils down to how porn affects you. If you find yourself 3 years into a long term relationship, and thinking "eh, I'll just crank one out now rather than go see the gf" ... it could be hurting your relationship. If you're late to work because you have to crank one out every single morning ... it could be hurting your life. If you sporadically crank one out because your gf is busy with something ... you might be ok.

After almost one year of the no porn diet, the notion of re-engaging a small amount of porn to see how it affects my suspected "bad" aspect above is not so distant. We'll see.

Just know your limits, and reflect on how it affects you, your life, your relationships.
