4 inches

Your dick is, just like the rest of your body rather small and you grow so few public hair that u shaved it all of, because it looked just stupid to you.
Always a little ashamed of your small manhood you gave your best to hide it whenever someone could possibly see it. Being ashamed of your dick made you also kind of shy towards girls resulting in you still being a virgin but maybe this year or maybe even today this will change.
You jump into the shower for a fast cleaning, dry yourself of and get dressed in some casual clothes.
Suddenly there is a knocking at your door.
