Hey, I'm a mother with overall two very healthy boys, one six years old the other two years old, in general I have nothing to worry about health wise but I have an issue development wise, more specifically penis size. As my first born grew older his penis never seemed to change in shape or size, my youngest is a different story, when bathing them it is clear whilst being the youngest my second born is the 'bigger' brother, my eldest has a penis that couldn't be more than 2cm however the youngest is already sporting a 3/4 incher, I didn't think with genetics and all that penis size could vary that differently, and more importantly that the youngest could be WAY bigger than the oldest? Is this something I should be concerned about?
