Okay, maybe a little off topic, but similar situation. I went jogging outside yesterday to do something about the holiday eating situation. Got a nice 4 miler in, feeling good, until I got home. I'm in Philadelphia, USA, and it was COLD. So as I'm back inside thawing, the head of my dick starts hurting badly. You know how your fingertips hurt when you get back in from the cold? Well, imagine that in a MUCH more sensitive area. Fortunately, no frostbite or permanent damage, but I may have to double layer my underwear for today's run.
