Biking Shorts and Rain

OK so I think it is important for people to learn a little bike short physics.
Bike shorts have a sponge like material from your crotch (in my case balls) to a few inches past your asshole, basically the area many refer to as the taint, barse or perunium, to help keep that area from chaffing or getting sore from riding. Now when the sky opens and pours a fucken river of water all over you, your special ass sponge, ends up holding 2 friggin litres of water. Yes and that what it was like for me today.
