Ready to begin a journey with concern

Hey everyone one, I just turned 20 and have fapped since I was 12. Now let me begin asking. I'm currently in a relationship and have sex maybe once a week or twice if we can sometimes. Now my first concern, if I orgasm during sex will it effect me from nofap? Or will I have to edge myself and completely stop until I dont have the feeling to orgasm and continue? Well that's my main concern. Now to continue my introduction. When I was 12 I loved to fap, so much that I would do it 3-4 times a day, which led to 5-7 times a day for almost 2 years. I didnt know what I was doing I just knew It wasn't right to be doing but kept doing it. Well since I did it so much doing it inside felt so weird, so i would attempt to do it outside by begging which my back porch, then to the back yard, and eventually in a alley behind a garbage can. Heck I would even sneak out at night so I could do it in my front yard out in the open like no one was watching. Well when I turned 14 i quit that habit because it was just not right at all so i would just keep it to the bathroom. I also managed to bring it down a notch by 3-4 times a day, by 16 I also began to bring it down again to 2-3. Then at 17 i met my current girlfriend. At this time I would at most do it 2 times a day, sometimes even 4 times if I really had to get the edge off but it was a rare case. Currently I am able to limit myself to 2 times max in a day. Well I would say more like twice in an hour as its usually back to back. About 6 months ago is when I realised I had the problem, I knew it was a problem but this is when I really began to notice I had a bad habit. Well one night I was just enjoying myself whole watching porn and I kept finding really food stuff back to back, and even looking for snapchat model nudes. I fapped 5 times within a 45 minute period. After that session I noticed my foreskin was itchy but I kept in thought it was probably from wiping with my blanket that already has dried stains. Well when I woke up in the morning it felt the same, i went to pee and got random morning wood, it hurt and looked and saw that my foreskin was chafed, with scabs around as well. I don't know why I chose to ignore it that night but I fapped just once but I didnt even finish myself because of the pain it was giving. Later on that week my girlfriend wanted to have sex, I didnt think much of it as I thought maybe the scabs on my foreskin might've cured a bit, I was wrong and the inside warmnes of the vaginal made it feel like I had icy hot on my foreskin. It was extremely unpleasureable. We attempted to have sex again a couple days later and again it happened. We just didnt have sex for over a week. Well after that experience something else happened. I used to be able to keep an erection after orgasm during sex. But after the experience I had from the chafed foreskin, I was no longer able to keep an erection. Anits been like that for 6 months. Ik really hoping that when I begin my journey of nofap that i would be able to overcome myself. Thanks in advance to everyone here that supports one another and especially to those who read my whole story.
