Uncirc'd people have their soldier protected, and therefore more sensitive. As far as "sanitation", if your cock gets dirty, you fail at being a guy. Never even had to worry about that sort of thing, and it never smells or looks gross. When hes standing at attention. he looks normal, and when hes a little tired, he looks normal. Circ'd people think they are in some special clique, but I think it's kinda weird. Girls I talk to think it's weird too, mainly because the guys behind the cock are usually jewish.
*no prejudice intended, but most of the jewish kids I know are the most annoying people I have ever met*
