According to Wikipedia, the average length of a penis is about 5.5 inches, and the average radius from the core center of the penis to the outside skin is .75 inches. Using these two numbers, we can roughly calculate the volume of the penis with the equation Pi times Radius Squared times Height (Pi x .75^2 x 5.5). This comes around as the average penis being about 9.72 cubic inches. Now we need the volume of the average adult male. According to Alex Schlessingerman's "The Physics Factbook", the average weight of an adult male is 154 pounds, or 70 kg. Weight is found by multiplying an object's mass by the force of gravity, 9.81 meters per second. If we take gravity out of the equation (through dividing 70kg by 9.81 m/s), the average mass of an adult male comes out to be about 7.14kg. Then, we divide 7.14kg by the average density of a human (which is 985kg per meter squared according to Wikipedia) to find the average volume. The average volume of an adult male comes out to be 0.0072516316 cubic meters. Using the 9.72 cubic inches found earlier (which we must convert to meters, making it 0.0001592823 cubic meters), we can find exactly what percentage of the male body is penis. We will subtract 0.0001592823 from 0.0072516316, giving us the number 0.0070923493. Then, we divide 0.0070923493 by 0.0072516316, giving us 0.978034970778163. Now we multiply this new number by 100, giving us 97.80349707781625. Finally, we will use the number 100 to represent 100%, and we'll subtract from it using the new number. 100 - 97.80349707781625 equals 2.196502922183747. If the penis is 2.196502922183747% of the male body, then that means traps are only 2.196502922183747% gay.
