The average length of a penis varies from 5.1 to 5.9 inches. I went for 5.5 inches to be safe average for us here. The average radius from the core centre of the penis to the skin on the outside is .75 inches. From this we can roughly find the volume with pi times radius squared times height. This comes around as the average penis being .927 cubic inches. Next I found the volume of the average adult Male. I had to first find the average weight of a Male, which according to Alex Shlessingerman’s “The Physics FactBook” is 70kg or 154Ibs. Weight is found by multiplying the object mass by the force of gravity which is 9.81m/s. Once we got this out of the way, the average mass of an adult Male is 71.4k/g. Then I found the volume by dividing this number by the average density of a human which according to Wikipedia is 95.8k/g per cubic meter cubed. The volume of an adult Male to be ~0.0072516316 cubic meters. Utilising the volume of the average penis I found earlier, .972, I get ~0.0001592828 meters cubed. This means the penis is ~2.19% of an adult Male’s volume. Assuming a lack of testosterone and Male hormones and an increase in female hormones makes a Male less Male or a female all together, balls ignored for ease, a trap is only ~2.19% homosexual.
