Erection
The angle that an erect penis makes varies from one man to another. If it is imagined that a man is standing upright and there is a horizontal line stretching out from the base of his penis, most men's erect penises point upwards from the line at a certain angle. However, it is common and normal for an erect penis to point nearly vertically upwards, nearly vertically downwards. The angle depends on how long a man's suspensory ligament is. The suspensory ligament is a band of tough, stringy tissue that joins a man's penis to the front of his pelvis.
