No thanks. I very rarely rely on porn, once or twice a year maybe, and I am fairly picky, I don't care much for fake things, studio lighting and oiled-up bodies pretending to enjoy something. That sort of thing does absolutely nothing for me. I was also not the subject, but nice attempt.
First, a different example. Let's pick a different addiction - gambling. It's a good one to contextualise against, because they are both building on the brain's reward system, and not some substance use. You don't need a gambling addict to admit that they are one for it to be true.
You drew a parallel between women who can't orgasm through sex with their partners, and OP who can't orgasm without porn. The two are vastly different territories. Can there be overlaps? Sure, but they are absolutely not interchangable. It's casually leaving behind important circumstances. Women who can't reach orgasm through sex with their partners can reach it through other means (of course, not a 100%, needless to say). Op can't get herself to have an orgasm on her own WITHOUT THE USE OF PORN. If you are physically able to have an orgasm, but the only and exclusive way to reach climax is through porn that IS porn addiction. Do you understand? That is the only thing that can reward her brain and body to the level of orgasm.
Taking a step back from OP herself, there are many-many couples (browse through mumsnet alone if you have the time to read a million threads about it), where a couple used to have sex in the past, and they both reached climax, and later, after one of them started excessive porn use, they were not able to orgasm any more in a normal way. What is the only thing that changed? Developping an addiction to porn. It's not that complicated, excessive reliance on porn rewires the brain, it is a scientific fact. Whether you like it or not.
