Is it okay, to have sex during reboot?

Hey, guys

Ive got a really big problem. I started with nofap actually in january, and even was completely abstinent from PMO for 30 days, until I came because of my girlfriend. Ive got a really bad case of ED, but for some reason, after 30 days of abstinence it was just getting better, until I came and after that point, my erections, weren't as strong, as that one time, when I hit the 30 day mark. Last weekend (on valentines-day) I tried to have sex with her, but because my erection weren't as strong anyway, and the fact, that she is still a virgin, I wasn't able to do it, and it probably was one of the most frustrating things i've ever experienced in my life. I tried to get it up multiple times, but my erections didnt last long enough and so we just stopped.

Of course I tried to speak with her about it, and I told her about my problem and she luckily said, that it didn't bother her that much and that it is okay. We then agreed on trying to wait another 30 days, untill she takes a preservative and we are really sure, that it is safe to have sex.

So obviously I managed to get a little bit more time, to get my problem under control, but honestly this experience really left me in fear, for the next time. So I was thinking about seeing a doctor because of my PIED and try to get a v-pills-prescription, to have a backup-plan just in case, that it won't work again.

Now Im only asking myself, if it somehow would be damaging my reboot process if I do so and If it is okay to have sex while doing nofap, even though the fact, that im only capable of doing so, by taking those pills. I mean of course it would be better to just grit my teeth and pull through with pmo, but Im scared, that I may lose this amazing girl, if I cant get it to work and it really is fucking with my head .

What are your thoughts on this?
