think thats shocking - an average babys head is between 13 and 18 inches and the shoulders are even biggermeasuring from shoulder to shoulder. Bill Cosby doesnt say birth is like squeezing a watermellon out of a hole the size of a golf ball for nothing. LOL

when measuring the tape measure wraps around not across the tip.

And yea it fits comfortably when you have two consenting adults.

From talksexwithsue.com -

a recent survey in the U.S. found that men believe that the average size of an erect penis is 10 inches. Women believe it's 4 inches.

Anatomically, a normal penis is 3-5 inches non-erect; 5-7 inches fully erect.
