A girlfriend trying to understand porn addiction

Hi everybody,
I'm new here and I don't really know the rules to introduce myself but I will try my best. I'm a 23 years old girl from France. My english is not perfect, you will probably found some grammar mistakes, not so much I hope.

It's been a year that I am in a relationship with my 5 years old best friend. During this past first year, I discover that my boyfriend was a porn addict. He had a lot of difficulties to explain it to me at first but then, he said that I am the person he can talk to, so to have a 100% honest relationship, he decided not to be ashamed to put word on the problem he is confronting and ask for my help.

So here I am.

I grew up in a little city in france with only my father as a parent. My father wasn't a big fan of technology so the first time I used a computer, I was 12-13 years old. I discover Internet at that age. Porn was not a thing I knew about. The first time I saw something was at 14, when I wanted to watch a movie at home, and I played a videotape (yet, not a big fan of technology) and at the end of my movie, there was like 2 minutes of lesbian porn that was recorded.. You know, the kind of videotape that you can record other things over and over again on it.. anyway i was a little bit chocked and porn was in my 14-year-old-mind disgusting.
I grew up my teen years pretty much typical, without looking at porn until my 19 or 20th years..
I remembered that during a summer, I was a little bit curious and decided to see what it was. I tried a lot of different categories, hoping to find something that I can like.. But it never happened, so I decided to never go to porn websites again.
Here is the all story of my porn video life haha.

Sometimes, Porn appared in conversation with some of my friend, and few of them thought I was the kind of girl that can be chocked to see a dick, or a naked girl... I will not discribed myself this way. When I see a naked body, any gender, I see the beauty of the pictures, the angle, the beauty of the body but I have not a sexual view on them. For example, on Instagram, I am following a lot of "Suicide Girls" and there photos, I appreciate a lot of them, but never in a sexual view. I am more like "Oh, I love her tattoos, her hair.. or the way the pictures is taken..."

Since february 2017, I'm dating my best friend. It was perfect.
I notice that our sex life was a bit different than with my previous boyfriends.
It was like "fellation is an obligation", "cunnilingus oh no, that disgusting", the speed of the penetration were very high, he was trying position I didn't knew about...
And then, he had some trouble to have an erection. At this moment, he tried to explain to me his addiction.
It's a very good point that he is aware of it. We had a lot of conversation, hours and hours and I tried to understand this thing that is pretty much unbelievable in my mind.
He decided to reduce the number of visit he's making on porn website, to reincrease the effect real sex life can had on him.
Our sex life is beginning to get normal, I am trying to explain him some "rules" that are in porn are not the same in real life.

I am here today to read how I can help him, to understand a little bit more what he is going through that maybe he don't know how to explain it to me...

 

Thank you ! Recently, we have talked a lot and I told him how I felt about this. I told him a found help online, and he said that he is ready to read some stuff. He asked a lot about what I've read, feels like he was asking if he is normal, if he is the only one..
I will continue to check different posts in here

Thanks everybody for answering my 1st post on this website !
