I have a Q: What the heck happens to male junk when you've been in for a cold water swim?
The biggest factor in the size of a man`s penis at any given time is blood. When a person is exposed to cold, autonomic systems partially reroute blood flow in their body, reducing blood near the surface in order to conserve heat. You might well have noticed that in cold weather your fingers and toes are affected most, since they`re pretty much all near the surface. As is a penis. Cold water has a particularly strong cooling effect because it`s excellent for both conduction and convection. Swimming would probably increase the effect further because a higher proportion of blood would be sent to muscles for the work they`re doing.
Since a penis is far more variable in size than a finger, the shrinkage is far larger.
Testicles will be pulled up as much as possible to maintain their optimal temperature, so they appear smaller.
