A member asked:

What would cause a new vein to appear on my penis ?

A doctor has provided 1 answer

Nothing much: Veins big enough to see can't just appear. This is an older vein now more prominent or just more visible. Possibly as a result of sexual trauma. Unless it is painful or associated with an unusual erection i would not pay it much attention.
