Floating in Flatline symptoms .

Ever seen a cracker right before it bursts? LMAO.
same thing happening to you my friend, do you get boners when you touch your penis? do you feel horny when you touch your penis or something rubs on your penis ? is it sensitive?
If yes, then everything is fine, all you have to do is wait, once the brain re-wire itself and once the connection is established between brain and your penis, you will gain your libido back and will have erections just by thinking about sex wherever you are whether in public place or in your bedroom.

If you touch your penis and it doesn't get hard or get erect then I would say there is a problem , that means you may require more time to reboot.

 

Its a process bro, Just hang on to your 50 days damn! 50 days is achievement in itself.
You are healing and rewiring is taking place, your brain doesn't know what to do so it is still playing tricks on you.
You have made your brain dependent on dopamine rush by fapping for Years and now suddenly you take back that dopamine all at once.

How would you feel if your legs have been cut off? You will be desperate right? Same way your brain is desperate right now, although the good things is , unlike legs, your brain has capacity to rewire itself.
But, it will take some time maybe months , but you have to hang in there without losing hope.
Brain fog is due to lack of dopamine, once your dopamine receptors get reset , your brain fog will be gone too and your libido will come back .

Dont worry about libido, im 100 % sure your libido will return back to normal as you said you had high libido for 3 days that means your brain is going back-and-forth between high libido and low libido and couldnt find a good spot so its still searching .

Now if you don't relase, your brain will upregulate your dopamine receptors (upregulate = increasing the number of dopamine receptors) because your brain will realise that it is not getting any dopamine from PMO, so it will become more sensitive to other dopamine increasing activities like laughing, exercising, music etc and soon you be completely fine.

And, once your dopamine receptors are reset, your libido will come with a vengeance since you have abstained for so long. And, im pretty sure you will not fuck up again so there is no chance that you can fuck your dopamine receptors again,
A new life is waiting ahead of you bro, just hang in there and dont give up.

 

You answered your question .
This is huge improvement, hang in there you are moving exactly in the right decision
having an erection without touching your penis is a huge improvement
