Uncircumcised M28, almost above average T levels, healthy diet and regular exercice

I have a left curvature since i’m 14. I saw an urologist at my 17 but he said it was psychological and that my penis was normal. Despite that, I always felt a really huge discomfort and I often have difficult times to stay hard like if blood do not flows as it should

It feels like my left corpus cavernosum is even less elastic with years and when the erection starts the right corpus cavernosum swells but not the left in which I feel some kind of strangulation which increases the curvature even more when the erection starts

Some days, when erected and trying to stretch / bend the penis a bit to the right, the left corpus cavernosum is so rigid it seems it can’t stretch anymore like a tendon

I’ve also not much sensations in the glans most of the time, i guess bad blood flow is the culprit

I have an appointment with another urologist in mid september but I’d like to take any advice or thought about this.. Thanks a lot in advance !
