yes, this is a well known fact. do you live in a cave? over time semen hardens into a crystalline structure that is resistant to water and therefore builds up eventually acting as strong as cement, completely closing off piping, only to collect more semen.
What if in 1000s of years archeologists find this and think america colapsed because nobody could stop masturbating. Like Easter island but with compulsive masturbating instead of making statues
BS. What the hell is crystalline semen. I have no idea where you got this information, or if you're not serious. http://www.brobible.com/slideshows/view/11-examples-clogged-dorm-shower-letter I'm sure they're all bogus.
Trolled, OP is gullible. Hell I saw one a few days ago with an Oregon St. letterhead, exact same wording.
