In order to maintain internal body temperature.
Since the human penis has no bone (many animals do have one), the size of the penis is very largely (no pun intended) determined by the amount of blood present in it. One of the abilities of the human body to protect itself from cold, is to sharply limit the amount of blood that leaves the brain and body core, which would normally go to the extremities and cool off quickly (starting with fingers and toes and gradually affecting the arms and legs as heat loss progresses); This means less cooler blood to warm up. As previously mentioned, the penis size is determined by the amount of blood present in it, and since it is one of those first extremities that suffers a loss of blood, it shrinks.

Why do penises shrink when in cold water?
Penises may appear to shrink in cold water due to the body's natural response to preserve heat and maintain core temperature. The smooth muscle tissue surrounding the penis contracts, causing it to retract and become smaller. This reaction, known as the cremasteric reflex, is a protective mechanism to keep the testes closer to the body for warmth and optimal sperm production.
