Normally, stimulation causes blood to flow into the penis, which in turn results in an erection. After ejaculation -- or if stimulation is discontinued -- the blood drains and the erection recedes. When priapism occurs, blood that is sent to fill the penis becomes trapped, causing the erection to remain without relief.
