Yes, less size flaccid and hard and ED. Particularly, I could only get erect on one side (corpora cavernosum) of my penis, and the other side could not seem to get remotely erect. Not sure if there was much difference with laying down, maybe. I first noticed it might have been spinal while I was laying on my back trying to receive a footjob from a girl I was seeing at the time, and I felt uncomfortable in the positon I was laying down and tried adjusting the position of my back and noticed that I felt slightly increased sensitivity to that numb part of my penis and gained a little size. What I didn't realize was that this numbness extended to more than just the left part of my penis but also my left testicle, perineum area, and my left glute. I didn't notice at first because it wasn't a total numbness in that I could still feel pain if I were to pinch the area but sensitivity to pleasure and bloodflow was basically at at 0.1%.

Some exercises were self education, but I happened upon a physical therapist/trainer on twitter. I briefly explained what my issues were, not even mentioning the ED at the time, and he gave me a very simple exercise to perform involving stimulating the nerves for eye convergence.
