Erections are not constant because the body has mechanisms that regulate blood flow to the penis.

Erections occur in response to sexual stimulation when these blood vessels relax, allowing increased blood flow to the penis.

During the erectile process, excess blood flows into the Penis causing the sex organ to swell into a longer and harder extension of the body. This can happen because of sexual stimulation, puberty, or "happy thoughts" ( lol ). The reason it contracts into its smaller self is because the blood is flowing out of the penis. blood flow and release to and from the penis causes it to expand and contract...
