The corpus men feel the most is the underlying corpus. So when there is no bloodflow one thinks, it is not detached anymore. The problem is, that the blood takes now another path:
After bowel movement my longer flaccid gets normal for a while
When my glans is more filled, the penis looks normal again
When my glans is more filled, I can do the “jump” with my penis while kegeling
When I get morning wood I can feel the both side-corpus very rigid (even under the sack) but the middle one is empty (even under the sack and near the anus (where the last end of the corpera is)
My doctor said, the problem is the blood taking a different path now (from the pudendal arteries and veins from the anus, over the pelvis and then STRAIGHT in the leg and not the useal way through the underlying corpus)
So I ask many what happens to their penis when they do perfectly executed deep squats as many as they can. When it behaves differently then you have the same symptom.
When you do an mri VERY important do it with contrast dry
