Haven’t masturbated and nutted in a month

I’ve been watching porn/masturbating since the 5th grade. I’ve decided to stop because everytime I’m going to have sex with a woman it’s hard to get hard, especially if I wear a condom. I need head for it to get hard and then when I’m having sex I’m so worried I won’t stay hard so idk if it’s in my head or from so much masturbation. I always feel more comfortable when it’s a GF but if it’s like a FWB I’m super nervous because I won’t stay hard or I cum fast so I won’t lose my boner. I’ve changed my lifestyle, been hitting gym, eating less and stop masturbating. But I tend to still see woman from OF, I sometimes watch Twitter, Reddit or telegram leaks. I touch myself a little, I get hard but I don’t rub all the way as if I’m going to nut. So it’s like maybe a minute of rubbing/touching my penis, I’m really anxiety because I feel like I want to bust my nut since I haven’t in a month. Will I get my erections back if I continue doing the things I’m doing? Or so I have to stop watching OF leaks/porn? I wouldn’t say I’m a porn addict because I never really liked porn, it’s more of the orgasm, I can literally nut in less than 30 without even clicking on a video and just scrolling to choose one. Is me not masturbating I guess fully and not nutting good? Or do i have to stop watching naked woman/OF sex leaks? Please I just want to be able to pleasure a girl with my penis and have the confidence that it won’t die while doing it. I always make them cum first from head incase I can’t do it because I go limo but still there’s times where they want to fuck and I do too but it’s hard/nerve racking. Any advice? Did you guys stop and get a hard erection again and if so how long does it take? Please help/give advice. I told myself I don’t plan on nutting unless it’s from sex/head.
