I just turned 15 about a month ago on the 6th of Sept. and my penis size is about 5 inches when i push down the fat thingy. is it normal to be 5 inches and be fat. im 6ft tall and 249 pounds with a 5 inch penis. Whats the average weight for a person my size and whats the average penis size for a person my size. im worried because i was told fatness can effect penis growth. Thanks
