Does a boy's penis grow steadily along with the rest of his body, or does it have a growth spurt when he nears puberty? Just a little concerned as DS#1 is a big lad in every other area but not, as yet, in that. It doesn't seem to be keeping pace with him - although I don't remember it being noticeable small when he was little.
(OMG DS would kill me if he saw this !!! ) I know it's probably daft and none of my business....
