Erection is defined as:
- the condition of becoming rigid and elevated, as erectile tissue when filled with blood.
- especially the swelling and rigidity that occur in the two corpora cavernosa and corpus spongiosum of the penis as a result of sexual or other types of stimulation. Impulses received by the nervous system stimulate a flow of blood from the arteries leading to the penis, where the erectile tissue fills with blood, and the penis becomes firm and erect. Erection makes possible the transmission of semen into the body of the female. Erection can also occur to some extent in the clitoris and the nipples of the female.[1]

Circumcised males may experience tight and/or painful erections if there is insufficient residual shaft skin to permit full expansion and extension of the shaft of the penis during erection. Tissue expansion may relieve the pain and tightness.
