I was addicted to internet P for over 12 years before I started to see the effects. I was edging for long periods of time, sometimes several hours at a time. Once I got into my late 30s, my functions finally gave out on me. All I can say is that if you keep doing it, it'll eventually catch up with you.
I'm 38, been PMO'ing since I was 12. 6 times a day is average for me. No ED issues so far. It's possible.
I don't have much expertise on this topic but I would assume that it depends on how frequently you PMO and how old you are. ED can come later in life regardless of PMO. I would imagine that PMO would cause the ED to strike you earlier. Also, every individual is different so some chronic PMO'ers could never see ED. It's possible.
I'm sure that with an overabundance of porn use you would be able to get hard enough to PMO. You would be incapable in an actual real life scenario though.
I'm not sure of the actual definition of porn-induced ED. Also, I don't know which one the OP was referring to in this post.
