I used to believe that penises had bones in them. Even at the age of 28, and having had some sexual experiences I still believed that this was the case.(Obviously,I had never seen a penis in a non-aroused state)So when a Jewish friend of mine invited me to her son britz I was alarmed! I thought how much pain will the poor baby endure having a piece of his penis bone chopped off!!
