I think you should DEFINITELY follow honeypot's advice and check out the procedure and inform your husband of it. Holy cr@p! Surely this would emotionally scar a little boy in some way???
Lou, I think the thing about the nerve endings is that with a guy who is cut, the head of the penis becomes less sensitive because it is OUT THERE in the world rubbing against clothing and such. A guy who is uncut would preserve sensitivity in the head of his penis, because it is covered by tissue (that's "tissue," not "a tissue") except when in use .
