Men, Don’t Forget: You Have Nipples
The photos below may be a little disturbing to some people, but they're a provide an important reminder: Men, don't forget that you have nipples too.
For those who may be unfamiliar with this phenomenon, it is called male nipple chafing, or sometimes, the "sad clown face". The repeated abrasion between the skin and a wet shirt (particularly cotton) over thousands and thousands of strides eventually causes the below to happen. It's completely preventable - band aids or a lubrication product called BodyGlide will usually do the trick.

You mean the abrasion between the shirt and the nipple is so severe that it causes the nipple to bleed???
This is the first time that I’m seeing this…

Wow. What’s weird is that they don’t even seem to realize that they are bleeding. That’s why we guys should only run shirtless. Give those nips some air.
