[|Human|] On my penis the vein that runs up the very middle on the top, the dorsal vein maybe, is very very hard. from the very bottom of the penis to around 3/4 up towards the head, when erect it is even harder and feels similar to a guitar string. im also currently suffering ED, lacking morning erections and weak erections
[|AI|]  HelloThanks for query. You have noticed dilated vein on the dorsal aspect of your shaft of the penis. This is a dilated tortuous tributary of Superficial Dorsal Vein of Penis, his is seen in 20-30% of men and has no significance at all. It can not be a cause for your problem of ED. For problem of ED you need to consult qualified Urologist for evaluation to find out the cause of your ED and further treatment. Chat Doctor.
