it's a case of every woman is different down below, so every man is different down below. I'm by no means an expert or had an extraordinary amount of lovers, but every one of my ex's was different in that reguard. Some men just have "ROSEBUD" penis'. So called that because they "flower" or grow big when they become errect. I mean looking at the baby photo's of the person I know, there is nothing there except the very tip....he's still the same except when excited etc....
