Well according to requirements:
To determine if a man is a grower or a shower, you can calculate the difference in length between his flaccid and erect penis:
Grower: The difference is greater than 4 centimeters (1.5 inches)
Shower: The difference is less than 4 centimeters (1.5 inches)
So I'm a grower according to that, though on soft I'm nearly as big as the average erect length so brunette says both.
