It is a lovely package you have there thatguy 101 but to really know how your size compares with the rest of mankind you should meausre your self. Get a tape measure ( or a ruler and a piece of string) and hold your erect cock horizontal, measure along the top form pubic bone to tip, then measure girth at widest point along the shaft. If you have callipers isolate one ball tightly at the end of your scrotum and measure its length and width and depth.
You look big but these measurements will allow you , and us if you care to share them, to place you self in relation to othe big guys.
Enjoy, develop and use of your sexual gifts to please yourself and others.
