Losing interest.

I had exactly the same problem, and it is simply a less severe form of ED. It's still erectile disfunction as the correct function of the penis is to remain erect until after ejaculation. For a year and half after I discovered nofap I suffered from ED (I still suffer a little if I attempt sex within a week or so of relapse), which gradually improved.

At first I couldn't get it up at all! then gradually I could get it up more and for longer durations until finally I could successfully have sex. The only way for it to improve is to abstain not only from porn but also masturbation, as the harsh stimulation desensitises the penis. I spent 3 years getting to where I am now with regards to ED and DE, with countless attempts and a personal best streak of only three weeks, I imagine results would have come much faster if I'd managed to abstain for longer (my average streak so far has been around a week or so). I still have a long way to go myself, but I can assure you that your problem is ED and DE and the best way to address it is through abstaining from PMO.

I hope this helps.

I'm glad it's helped. You'll probably realise with time that even now the levels of arousal your achieving with porn/with a partner are still around 50% or so of what they will be when you're on a long streak and are intimate with a partner. There's a significant margin between getting it up to a level where it'll work and being fully excited.
