No difference except the people who were circumsized have a lot less sensation. SUCKS TO BE YOU BITCHES HAHAHA.
But no... really the head of the penis keratinizes and becomes hard and thus less sensation. It really is a thing of the past and should've been discontinued much like declawing cats. UNETHICAL American tradition.
while it is more important to keep an uncut penis clean, fif this is done, no, about the same. however, the term smegma comes to mind..
also, the 'bigger' myth is just that.
how many porn stars are cut vs uncut...?
that said, women get smegma too and still like to get a man 'down there' w/o thinking about how gross it can be...
