Can't Orgasm During Partner Sex

I'm 23 years old an recently got into my very first relationship with a guy. I lost m virginity to him too. The first time we had sex, I realised that it was a challange for me to orgasm. I was a bit concerned but figured that it was my first time so it is to be expected.
Yesterday, we had sex again and I haven't had an orgasm again. At this point it was very embarrassing for me. I tried various things and positions and still didn't have the urge to release.
Sex ended on a sort of bad note because he felt like it's his fault he can't satisfy me. We kinda had a heated discussion about whether I was attracted to him or if I had someone else.

This whole situation is really bringing me down and has been on m ind all day. I really don't want this to affect our relationship.
I started doing my research and came upon the idea that porn could be the reason for all of this.

You see, I have been watching porn constantly for almost 5 years, everyday. It came a point where I was having an orgasm to porn up to 3 times per day.
Could my dependency on porn for the past couple ears be the reason for this?? Someone please help me because this is having a really bad effect on me.

Well this entire problem is getting in the way of our relationship. We haven't been speaking much and he is upset with me. His whole idea is that I am not attracted to him the way he is to me and that's why I can't orgasm. He also thinks I'm in another relationship. It really is stressful but I just wish he was more understanding.

Thanks for the motivation though. It has really been taking a toll on me. Good to hear that there is a solution and things will work out.
