Dusty says he'll be fine and I'm sure he'll be fine but :P
At the same point in his life where my darling son has starting full hand twisting pinching, he's found his penis. Which is totally cool (well, if I get to it first to clean off the pee/poo) but someone please tell me that I don't have to worry about him pinching it off or doing damage. He grabs a nice handful of scrotum, too, though he doesn't seem as pleased with that.
I want him to have a fabulous relationship with his penis, not one that requires repair ;)
