Considering that his body proportions probably skew the visual perspective, I would say that he is just above average but if adjustments are made for height and the length of his limbs then he would probably be considered "typical" . . . although some Michigan co-ed probably wouldn't kick this fly specialist out bed since above average still feels above average, especially when attached to gluts that have been trained for endurance.
. . . As a side note, I learned to swim when I was 10 years old then went on to 7 years of competitive swimming. You know how my swim teacher, a 16 year old preppy male lifeguard, taught me how to do butterfly, he literally said, "Pretend like you're fucking a girl."
