A cup of ice cold water!?
Just for your own consideration - a principle to follow.
Don’t let your dick turtle - maintaining an ‘inflated’ size will only benefit you positively, or at least more than making it shrink.
Cool-downs aren’t meant to be taken literally as to include cold water. Use a rice sock or warm water for a cool down.
Just a thought.
Actually, a cool down means exactly what it says. What you’re describing would be a warm down.
Ice cold water (doesn’t have to be ice cold) or a ‘cool down’ actually prevents turtling because it effectively makes the tissue hard while still in the stretched state. Otherwise, if the tissue remains warm, but is no longer being stretched, the same elasticity that allowed the stretching will now allow it to retract and ‘turtle’ as much as it wants. Capeche?
