hi, i'm 15 years old, and i'm about to turn 16 on september 20, 2009. my penis size when NOT errected is 2 and1/4 inches while i'm STANDING up from the tip of my penis to where i can feel the SKIN on my pelvis. and about 1 and1/2 inches while im SITTING down when NOT errected from the tip of my penis to where i can feel the SKIN on my pelvis, its a big difference because i'm over weight but not super fat, just fat so it seems like there is a lot of fat around my pelvis area that makes my penis measure a lot smaller when im sitting down. and even also when im standing up.... but if i STAND up and measure my penis from the tip of my penis all the way back until i can feel the BONE on my pelvis while im standing up it measures about 3 and1/2 inches while NOT errected. and when it IS ERRECTED and i'm standing up, it measures a little over 5 inches when it is measured from the tip of my penis all the way back until i can feel the BONE of my pelvis, not the skin.....and if i measure it when IT IS ERRECTED while i'm standing up from the tip of my penis to where i can feel just only the SKIN of my pelvis it measures about exactly 4 and1/2 inches.........is that normal average?? is that preety good?? or is that small?? or too small?? what is the average for my age?
