i think i got ED

its about to be a week and what i can say is that it was a pretty bad week for me, relapsed 5 days ago and broke a streak of 5 days, and i went for a FAP FEST subsequently, i literally wanked of so bad. last night i realised that i wasn't able to get it up to a hardcore porn. now i have another reason to do nofap....i think i got ED. I wish i were wise enough to understand this beforehand.
well i guess i will have to give up porn entirely rather than convincing myself falsely that I'm trying to give it up.
how long does it generally take to have the regular libido? i'm 20.
