Erection is caused because of the flow of blood into the penis. The flow of blood is caused by having sexual thoughts or due to the stimulation of the penis. When a man is sexually turned on, he wants his muscle to relax which increases the flow of blood into the penis. The flow of blood caused the chambers to fill with blood which makes the penis hard. A man loses is erection as long as the muscles start contracting. In that case, the blood starts flowing out of the penis, making the penis soft again.
