The problem with a pornography habit is the impact it has on the relationship. Different people have different realities, and not all porn users become porn addicts. When your partner ignores you in favor of porn and it ends up with an absence of physical and emotional intimacy within the relationship, then porn is creating serious problems. If a man ends up with erectile dysfunction every time he attempts to have sex in the real world but can 'perform' OK with porn, then porn is a problem for that guy. We hear it over and over from women?porn turns men into lousy lovers. Porn isn't sex so when it comes to the art of lovemaking they don't have a fucking clue.
As for the 'abandoned' female partner only being upset if she has self esteem issues, it's not that simple. It's more likely that low self esteem is fuelling the guy's porn habit which in turn fuels his own feelings of inadequacy. As does the erectile dysfunction that eventually happens from habitually using porn. The research into porn addiction explains how the endless novelty of a never ending supply of supernormal stimuli conditions the brain and fucks up the brain's natural reward system. A man hooked on porn is effectively a lab rat, or like one of Pavlov's dogs. He starts responding to the anticipation and seeking activity. There isn't really anything sexual happening. It's just a guy with his dick in his hand staring at a screen.
The damage to the relationship comes from a lot more than just the viewing of porn or the masturbation, as the others have said, they hide it, they lie about doing it, they prioritise it over other activities, they set aside time to indulge in it. Writing this, I'm like "was this REALLY going on in my relationship?" Unfortunately, yes.
OK, on to the debate about whether or not we take it personally. Yes and no. I understand "it's not personal" in that it's a weird mindfuck that becomes compulsive and leads to addictive behavior for some people. In that sense, it's not personal. In fact, it's a very impersonal activity. In that respect, it's about as personal using a vending machine or something, I suppose. BUT it takes so much energy out of the relationship. The guy hooked on porn is actually the one who is neglecting the sexual part relationship. He's the one who isn't available. Eventually he becomes more emotionally distant too. Obviously the female partner is thinking "WTF is going on? Why is he not interested in me any more? Why is he having problems staying erect? Why can't he finish?" All the classic symptoms of porn addiction, but typically she doesn't know about porn addiction at that point. Some women might not have a clue her partner is using porn regularly. I knew my husband was using porn so I knew that he was obviously getting off to it, so I believed that I just didn't have "it" any more. That was what damaged my self esteem. Learning the science behind porn addiction taught me it wasn't a judgement on me.
In this community, we all have very different experiences, different attitudes, different ages, different cultural backgrounds, different personal situations, but we have all been in relationships that have been disrupted and sometimes destroyed by porn addiction. We are all here because of our relationships. If we choose to end that relationship, we would no longer be the partner of a porn addict. Problem solved, eh? Lol. Joking aside, being in a relationship with a porn addict is not for the faint hearted. You have to be strong willed and resilient to weather something like this. Staying is a choice. Leaving is a choice. You can't survive staying or leaving unless you believe in yourself and that negates all this "porn is only a problem for women with self esteem issues". Once you face porn you soon see who's the one with the REAL self esteem issues and 9/10 it's gonna be the guy with his dick in hand staring at a computer screen. The guy who's lost his mojo. And it's almost always the woman who sees the damage it has created.
