Erection Any type of stimulation perceived as sexual can cause an erection; spinal reflex Erection also occurs during REM, possibly to keep the penis supplied with blood Nerve fibers open the arteries of the penis to allow blood to flow into the 3 cylinders Veins compress to prevent exit of blood Flaccid state returns when arteries constrict and the veins open to allow blood to flow out
