many, many studies have been made and there is connection between height, foot size, nose size, hand size.
I'm fairly certain there was a typo here. There is no connection between penis size and any of the other attributes mentioned, height, foot size, nose size, hand size. I've seen guys who are over 6.5 feet tall with small penises, and guys under 5.5 feet tall with relatively large ones. Big feet/hands and small dicks, and vice versa. These are not connected at all and the research proves that do be the case.
