Porn makes you impotent
That I struggle to cum when having sex but have no difficulty when watching porn
The myth or need to be so visual that you need to see her genitals.
The type of porn I have ended up watching after 20+ years is now porn that actually addresses and confirms my anxieties - your dick is too small, you can’t please women, you’re not good enough, you’re a loser. Ironically, this makes me excited. But it’s just my anxieties being confirmed which almost feels accepting.
My “addiction” to porn comes from just boredom and prolonged isolation. I don’t get to see my wife for days on end and fill the void of time with porn if I’m not busy. Now that I’m having erection issues in bed but not when I watch porn alone, I was worried unrealistic fantasies were being built up by the weird shit I was watching.
Porn opens up dangerous gateways to kinks that can ruin intimacy. The content I find myself watching is more extreme than anything I would attempt with my partner. 
Porn is directly responsible for shaping unrealistic expectations, and beauty standards too.
I do still feel the destination piece can come from unhealthy habits still. I think going through some of these claims and debunking them as myths helps me understand that with better habits and less reliance on porn to feed sexual desire, that desensitization doesn’t have to be an outcome of just enjoying something exciting when you feel horny.
That it’s pprn causing my lack of erections.
