Hello everyone , I want an advice or help because I dont know what is going on.. I heard nofap and the consequences of porn so here I am for your help fellas. I am in a relationship for 5 years , the girl I met at first was hot af 40-43 kg 1.50 , now shes 60 kg and it is a huge turn off because she put weight in her belly only and her ass is flat so I dont have physical attraction to her anymore , i am never horny and i always look for porn to find and masturbate to all the perfect girls and bodies and aaall the fetishes i have in my imagination. Okay but now we dont even have sex , in fact we CANT because im always soft or if im erected I lose erection during intercourse in the next 5 min.. I love her but I DONT like her so I cant leave her because shes an amazing person and always support me.. I feel like porn ruined me because I think I have PIED , but I dont get it why before I was always watching porn and was HORNY AF and even had sex for 1,30h + is the problem that Im in longterm relationship and you get fed of someone or its just porn fucked my dopamine?? I was horny af during my 21-23 years old like damn , now I am 26 and I feel like an old 75+ No-testosterone old man trash. I tested my testosterone it was from 8 - 29 mmol or something like that mine was 25.9 so its completely normal. I feel really confused and I dont know what is the problem - is it that my gf gained weight ?? is it because I watch porn every 3-4 days and PMO if yes Why I could watch porn every day before and be horny alllll the fukin time and never had any issues and now I am an impotent scrap , OR its because I am in a longterm relationship and its normal?? Please friends , tell me if someone experienced the same thing and how can I fix myself , I am also playing a lot of video games idk if that also contributes to my burnt dopamine. I am so doomed and addicted to porn that i sometimes think about leaving my gf and getting a sex doll with perfect big ass and bang it while watching my fav porn scenes , I once done it while I was away from my gf for 3 months and I got a sex toy ass and it was amazing and better than real life sex , that how doomed I am.. EDIT: When I cant have erection and every time I do PMO after that I treat my gf very bad I mean I am ignorant and I feel like I dont need her anymore and always try to fight with her , not in a mood for anything, dont wanna spend any time with her and deep inside it makes me sad because I know it is very wrong and she dont deserve that , I dont know if its all a side effect of porn..
