Hello Axe.
Welcome.
Of all the things to be insecure about or hung-up about one's self, penis size should be pretty low on your priorities.
You have no control over your height.
You have no control over the size of your feet.
You have no control over the size of your hands.
You have no control over the size of your head.
And unfortunately you don't have much control over the size of your penis.
Instead of worrying about things that you have no control over, concentrate on those things that you do. Live well, treat your self well, treat others better, take care of yourself, and try to leave the world a little better than how you found it. You might be surprised.
Pax.
