If you ever forget how metal the uterus is, remember that doctors used to think this thing could traipse around the body
(lemmy.today)
This is outrageous but testicals do wander a little. Go into a hot space and the wander down a little. Go into a cold space they wander up. If they wander into your body see a doctor though. If they wander by spinning and get wrapped up in their veins see a doctor immediately!
