It's called "How Not To Orgasm". All of these would be rather deflating and embarrassing. Although the reference to Rammstein wouldn't be too bad. It would confuse the wife though.
What would be worse is thinking of Rammstein at the point of orgasm. Or, having them in the room with you.
Why would Bill Gates want to award $100,000 to someone who can find a better way to put on a condom? Sounds like someone likes to go bareback but had a little scare. Actually that's purely disgusting speculation on my part. You can find out why here.
I'm guessing the last thing a guy would want is to have a condom applied by a wooden slingshot. Unless you're into that kind of thing? I'm not judging. But Slingshot Genius Joerg Sprave crafted just that. Watch as he describes how the Spanish Inquisition-type device is supposed to be used while laughing like Ernst Blofeld. I'm guessing he hasn't tested the device on himself. He seems smarter than that. If he had some kind of automatic repeating device for this and came with a tube of lube, he would sell thousands.
