An Negativeboner happens mainly when a man is exercising and requiring blood flow to go to other part of his body besides his penis. This does not happen to all men. The guy's dick shrinks up to the size it was when he was 3, and sticks straight out, making a prominent small bulge in pants like gym shorts or swimsuits. This happens to men of all sizes (penis wise) and is really embarrassing and aggravating. They mainly occur during high weight or high intensity workouts, or cardio.
