A human penis does not contain a bone – it becomes erect by filling the sponge-like material in the penis with blood. Despite this, it is possible (in a sense) to break this vital part of your body. A sudden blow to the penis or sharp shock or bending can break the fibrous tissue that contains the spongy material (called the corpora cavernosum). Unfortunately (and rather embarrassingly for many men every year) this requires a trip to the emergency room as only surgery can repair a broken penis. Left uncorrected a man can no longer have an erection.
Interesting Fact: Contrary to popular belief, men do not need to masturbate or have sex regularly in order to prevent “blue balls.†Excess of sperm is handled (so to speak) naturally by the body by releasing it into the urine stream. --
