A man without a penis has had sex with more than 100 people, while somehow managing to conceal the fact that he's missing the critical organ.

Andrew Wardle, the subject of an upcoming one-hour documentary special on Discovery Life Channel, suffers from an extremely rare birth condition called bladder exstrophy, which caused the organ to grow outside of his body. Doctors managed to fix his bladder, but he was never able to grow the male reproductive organ. He does, however, have testicles.

The documentary will follow Wardle has he confesses his secret to old friends, past lovers and flings and even his current girlfriend, who has no idea. He admits that he has revealed the truth to some women, but it didn't always go as well as he had hoped.
