Think about it like this.
If you don't have a significant other--and many do not, we kind of need to stop the shame about that--then porn is an inadequate substitute.
It's like dry gulping to a video of steaming roast chicken, and somehow convincing yourself it's 1) satisfying, and 2) self-respecting. Just like the real thing, he says. Thanks goodness for porn.
Uh, no. Not really. Self-respect is pretty important. It's hard to have self-respect when the above is your go-to.
If you're having problems finding a significant other, and are using porn as some kind of stop-gap, then trying to curb your use will be very good for you, whether you succeed, are kind of successful or not very successful at all.
It's pretty much the only biological urge that is not essential for personal survival. So while it's as insistent as some others, it's not needed.
Also, consider that many men, maybe you, are in fact looking for love, but there's no substitute for that, so the subconscious reduces this impulse to the next available analog.
I think once people figure this out--that for many, lust substitutes for love because love is unavailable in substituted form--maybe some of the shaming tactics over porn addiction might be exposed as mean-hearted, at best.
