hello, I am a 28 year old M

these past 2 weeks have been hell for me, I'm usually very sexually active, I get Morning erections that leak with pre cum and every time I watch porn or I close my eyes and fantasize I get erections without even stimulation

last 2 weeks while I was shaving my pubis, I grabbed the tip of my penis and stretched it while shaving towards 3 positions left, down, right.. since I was focused on shaving I didn't mind the pressure or how long I was stretching. After that I've waking up during the night due to pain and lost all my erections, I can't perform anymore my penis just gets semi-erect at the base while the 50% upper half just flaps. I went to visit both GP and URo and both told me I have nothing, that it's psychological, that there's no visible bruising That I'm making this up.

It's driving me insane all this, I'm just sitting and crying in my room the whole 2 weeks, did someone experiment with the same issue at some point will I recover my erections

Thank you and sorry for my English

edit : did read on the internet that what i unconsciously did by pulling my penis with strength while shaving is a dangerous "exercise" and apparently some men engage in this exercise to improve their penis but it has high risks like permanent ED . I hope its not my case, but I forgot to mention that i started getting urinal problems like difficulty pushing and even leakage when handling my penis just 1 day after .
