if you look at your penis from the top go straight to the botton of the shaft, at the top where the shaft meets your body and hair, right in the center if you push
in and down, towards your anus, there is a very hard
lump connected to a tube or
vein. The
lump is about the size of a pencil eraser and very hard. When soft I have no problems with it but when erect it is very painful...very much so if the penis is pulled downward. Thanks for any help.
