How did porn affect your sex life?

For me it has had many terrible effects. First of all severe DE, no sensuality while having sex, no passion, no intimacy, no desire at all to give pleasure to my ex-gf. It would even piss me off to have to touch her vagina and clitoris. No foreplay at all, I would try to penetrate her almost instantly. I was focused only on my pleasure and her pleasure did not matter at all. I was thinking about my favorite porn while I was having sex with her, sex was basically glorified masturbation. I was never able to make her reach orgasm once because I was so focused on my own pleasure.

All this led to our break-up 4 months ago after 3 years of the most toxic relationship I have ever been involved in. She was not very understanding of my addiction and towards the end she was very judgemental and she was shaming me. But it did take me 2 years to admit my problem so she had had enough I guess. Porn basically destroyed my relationship.

I'm now 29 and I remember when I was younger around 16 I used to be way more passionate and foreplay lasted around 30 minutes during my first sexual experiences. Back then I wasnt addicted to porn. I'm worried that this will never get back to normal especially now that I don't have a gf to re-train my brain gradually for normal intimate sex. I wonder if I will ever get turned on again by pleasuring a women like I used to when I was a teenager... What about you guys how has porn affected your sex life?
