Hey guys, just looking for some guidance and reassurance here.

I'm in this physical relationship with this woman right now where we only meet up to do sexual shit with eachother. If she gives me handjobs my dick can get hard but it goes soft in her pussy and when she's giving me head. I haven't jacked off in almost two weeks, I only jack off in the shower with generous lube, and I haven't watched porn in like a month (that was the last time I relapsed, before that, no porn for another month or two). Again, handjobs are mostly OK, I can get hard and last a bit with that, but the wetness just puts my dick to sleep, and then I get anxious because I'm fucking up and then off we go with the downward spiral.

Here's my understanding of how to fix the issue: don't watch porn or jack off for a few months straight, OR don't watch porn period but jack off occasionally with lube or a fleshlight. Should I just stick with nofap noporn? Is this thing gonna set itself right eventually? I've been meditating an ass ton today to just ground myself and dump the anxiety, because that will hold me back for sure, but I feel like there's still just a piece of the puzzle missing.

Background info: straight virgin, gone soft on like 8 different chicks, just couldn't fuck. Stopped watching porn everyday back in October, and every moth or so I'll relapse for a couple days. Do I just need to stick it out for longer and I'll be fine? I'm going to the doctor this monday and I'm going to ask for viagra to try to get my shit working in the short term, but I'm kind of scared. When my dick was getting hard with handjobs the other week I finally was like "thank god, all that shit is over", but when she tries to get me to cum I just don't make it there. Blowjobs make my dick soft after like 5 minutes, sex makes it soft after like a minute. So my current understanding is I still have some deathgrip issues from my porn infested jerk off days, but will that go away after a while of just nofap noporn? What about my anxiety? Any tips for that?

I'd just like some reassurance from others on my approach to cure my ED and guidance from those who know what to do. Thank you guys so much.

edit: I have the willpower to get through nofap noporn for a few months straight. I know I can do it. I've gotten a lot better at meditation and my willpower is increasing as a result. I'm just kind of scared to be honest and I just want reassurance that I'm on the right path and any guidance people have to offer. Could it take even longer than a few months? I'll do what it takes I swear to god, I'm fucking done with this shit, I just want to be told some harsh, blunt truths about my situation and what I need to do so I can stay focused and make it there. This fucking sucks.
