Over the weekend we heard a penis transplant on a 21-year-old in South Africa had apparently been a success. The subject has been firmly on the agenda with a couple of big stories over the last few weeks. We all know that penis size is one of men’s greatest obsessions but most don’t know the surprising truth behind the size myths.ĭid you know, for example, that humans are better endowed than all our primate cousins? You may expect a gorilla to be better hung than you but you would be wrong, both in terms of absolute and relative size.
