There is quite a lot of discussion on the forum about the size of the glans - especially the girth but I couldnt really find anything about the shape. And yet this seems to vary a lot between individuals. Not long ago, in the showers after workout, I found myself next to a man with a good sized cock - 6 inches/15 cm vicinity. What surprised me was when he pulled the foreskin back to wash, and revealed a very short glans. It was not small it looked quite a bit thicker than the shaft but it was very short, a bit like a shell. Mine is just the opposite long and tapered at the end, and Ive seen other shapes which are different again. The only site I know that describes some of these different shapes is the French Tailles: http://www.mesuret.org/tailles/glands.htm but Im sure you must know others, and Id be interested to exchange anything on the subject. It may also be that in a country where most men have foreskins that completely cover the cockhead (or almost) its hard to get a complete idea of all the variety.
