TITLE: TIFU by using a new type of shaving cream.
POST: I was about to hop in the shower when I looked down and thought, "Dang." There was some serious manscaping that needed to be done. I walked to the sink, and to my demise, I was out of shaving cream. "No big deal," I thought to myself, "There's more in the closet in the hall." I walked to that closet and I grabbed that first can of shaving cream that I saw. 

"For Sensitive Skin," it said.

"Cool," I thought, "I've always had pretty sensitive skin." By now my shower had heated up and was at the perfect temperature, and I was ready. With razor in hand I lather on a glob of shaving cream and begin to shave. All was going perfectly until I finished shaving and started to shampoo my hair. Something felt tingly and cold, almost like icy-hot. It was subtle at first, but then got stronger and stronger. My balls were blazing-cold as if it were a flammable ice cube. "WHAT IS GOING ON?!?" I agonizingly yelled inside my head. "This shit **HURTS**." I tried scrubbing off my nuts with some soap, but to no avail. Hot water didn't help, either. I was devoid of mercy. Helpless. *Vulnerable.* 

I toweled myself off and climbed out of the shower, frantically thinking of what I could to to end what felt like Queen Elsa and Satan taking refuge inside my testicles. I tried not to think about it instead, threw on some pants, and walked downstairs. I saw my mom and hesitantly said, "Hey, mom.. I used some of that sensitive shaving cream on my..face... and, uh, it kinda feels like icy hot..What's going on??"

"Oh," she said, "That stuff has menthol in it; your father bought it and I have no clue why. It should feel normal in a few minutes."

I receded back to my room and after about 10 minutes the feeling started to reside. 
And all was well.
TL;DR: 
I used some new shaving cream on my nuts that felt like Snow Miser and Heat Miser duking it out.
