Well I have one funny story, not sure how legit it is because its kind of legend but here goes...
There was this one guy in military training, training in the Borderland forces.
They were having an military training camp in the forests at winter and he was been on guarding duty for a few hours in the night, dark and cold as fuck. His hands had been numb because of the cold weather.
When his guard shift ended, he went to his teams group tent and was trying to get some sleep lying there.
Suddenly hes friend laying right next to him, woke up and started talking to him.
"Cant sleep?"
"Nope"
"Masturbating?"
"Yup"
"No hard on?"
"Nope"
"What if you tried wanking with your on dick"
I have no idea of if this is true or not but this is an old army story/joke that have been circling around very much
