From the "shit about aging no one tells you" database: Men's penises can become crooked as they get older. Peyronie's disease — also known as "partial penile disassembly" — is a condition that mainly affects middle-aged men in which an abnormal curvature begins to develop due to plaque, and can make penetration difficult. If you think that's a mind-fuck, how about the fact that a dude who wrote the article about it happening to him has been HIV positive since 1981 and is still alive! [Salon]
