Hi there ~
I understand your concerns. I believe that you may have a problem with fibrosis of the penis which is very common in peyronie's disease. However since you have had a history of priapism
that lasted 36 hours and have had a physical drainage of blood to undo the condition, it might be best for you to have the situation evaluated by another doctor, i.e. take a second opinion
regarding the actual condition from a qualified sexologist
. I believe that you also have erectile dysfunction
when you say that "penis does not bend up or down". If this is the case you will do well with medications for the same by consulting a qualified doctor or a psychiatrist
. I hope this helps.
Take care and have a lovely day!
