I am circumcised but i have a little hole in the shaft of my penis that cuff or covered by skin i clean it it has smelly discharge what can it be?

Here are some ...: Most likely what you described merely represents a small opening sebaceous cyst, in which the reaccumulation of smelly cheesy material will continue after being manually expressed out until its lining is removed or destroyed. But, clinically, it's harmless and needs no intervention as long as being comfortable. More? Seek pro-inspection and palpation timely.
