With penis size, are some of you guys too lazy to Google? To do a search on "penis size statistics"? Also what sort of measurement is 5 inches? 5 point what inches? Give us a measurement to the nearest couple of millimetres. Fractions of an inch between 5 and 5.5 inches makes the difference between being bigger than 38% of men and 68%! The average penis size is 13.1 cms - NOT 15.2 cms (6 inches).
the UK average is 5.1 i believe so you are definitely average. a girl i know once said to me when she was talking about what she thinks about **** size is "as long as it it longer than their middle finger they are fine".
At 15 you shouldn't be too concerned. As the previous post has said - you've still a lot of growing to do. Average adult penis size in the UK is 6 inches I believe.
