Hi I have similar symptoms. My glans also is pretty cold. My doctor is now checking for different bloodpaths my body takes. Here is my current history
What he said
He looked at my penis and said it looks like someone stepped on it. He asked if I had any pain and then touched it and said its indeed cold.
First I had to make basic moves where he after checked my penis:
Walking around
Sitting down then standing up
Rest on my back then standing up
Jumping and then walking
When I sat down and then stood up my penis was coldest. Then I had to lie down again with my legs angled and he pressed with two fingers under my scrotum and near bulbo-urethal gland. Then whith a little pencil-like device he tested the big vein on the back of the penis but there was everything fine, but to that point later.
So here he said there is indeed little blood. Then I had to stand up again and to kegel and there was no “jump” you know. It got shorter but it didnt jump up, I asked nerve damage he said its hydraulic, with little fluid there is no jumping up, but he tested the pudendal nerve anyway. The point of comparison is the tip of the indexfinger he said. Mine was 10 times slower than my finger but the scale is measured by normal normal glans. So I don’t know..
Then he made an expensive test I had to pay where he injected me something to get an erection. But before he did duppler ultrasound for ipp, because the test is not healthy fo ipp diagnosed people, can make things worse, he said. But no ipp found
I was on my back when he injected me this stuff and my two top corpus got instantly hard while perfectly hard but then when the doctor touched the one down at the urethat I was very shocked because its not like just the glans how I thought it was the whole corpus that was deflated. My theory was that I damaged the vein on the top of the penis somehow but the missing missing “tissue” is the blood in the corpus. When I felt them the way down to the bulbo urethal gland a could feel the middle corpus missing. Not just in the penis, even between my legs. Imagine a hot dog with the sausage missing.
The doctor pressed again with two fingers from my penis down between my legs and said somehow the bood takes a different path now. I had to stay in the office for an hour or so for the erection to fade.
So he searches now for different paths.
My current symptoms are
When glans is filled my penis doesnt hang so much
When glans is filled I can do the “jump” while kegeling
My glans filles more while having bowel movement
Also important to say that the underlying corpus is the corpus men feel the most. Thats the reason penis feels detached when the chamber is empty
When I do deep squats as many as I can I can see my penis behave differently when my injury happened
I have a new appointment for contrast dry MRI of my pelvis
