Wow . . . . just wait until you're an adult! How big around is it? Have fun, play safely, and don’t play with fire!
If you can figure out how to measure its length, you should be able to measure its circumference. Enquiring minds want to know.
I was being diplomatic. Why is it that the claim for an average penis size always seems to be typically 8"+. I've been with quite a few men in my time, and have rarely come across anyone better endowed than myself, at about 6½" - 7" (depending on level of arousal), with a similar girth - although the few that I've met that were longer also lacked in girth, so overall cubic capacity was probably about the same. Face it - the GENUINE average adult penis is about 5½" - 6½". Girth (which, quite frankly, is more important anyway) is usually about the same, if not, slightly less. I don't know if it's true or not, but I once heard that the reason men often tend to exaggerate their size is that they feel that when they look at their own penis, it's smaller than the others they have seen when, in reality, this is an optical illusion caused by the angle of view. When looking directly down at your own penis it looks smaller than someone else's of exactly the same size, simply because of perspective. Then, when they come across someone else who is suffering from the same inferiority complex, for the same reasons who claims that their penis is an average 8", not to be outdone, they also claim the same, and so the myth of the average penis being 8" is perpetuated.
