Speed of Cum

My medic freind told me that cum flies out of our penis at 45mph. Learn something new everyday.

45mph is about 20m/s. Gravity is roughly -10m/s^2, so it would take two seconds after ejaculation for your cum to hit its apex. At that point it would have gone 2s * 10m/s = 20 meters.

That would be a pretty nice shot.

(Note: Assumed that you're shooting straight up, because sitting is the correct position for masturbation.)
