On the subject of stings and nether regions.
Many years ago in Malaysia my mate was cleaning the cockpit floor of a Mirage after the pilot spilt a can of Coke while he was sitting in the aircraft on standby.
At the time, working dress of the day was a T shirt, Stubbies shorts (sans jocks) and safety shoes. He was crouched in the cockpit facing aft and reaching under the ejection seat to wipe up the Coke. The cockpit is extremely cramped so he was essentially squatting so he could reach under the seat.
The Coke, being a sweet sugary substance, had attracted a Malaysian hornet (big black and orange bugger) who must have been feeding on the Coke.
In an attempt to fly away after being disturbed by the cleanup, it flew straight up the leg of D's shorts. Being in a confined sweaty place apparently didn't please the hornet so it proceeded to sting everything in its immediate vicinity, which happened to consist mainly of genitalian real estate.
Hearing screams I thought no man could ever make, I ran over to his aircraft and with some other guys helped him out of the cockpit.
He was in agony and had made it worse by trying to swat the hornet while it was still in his shorts.
We got him into the flight line jeep and over to the base hospital where the medics took over.
He told us later that if he'd had a gun, he probably would have shot himself the pain was so bad.
