This is amazing (picture is NSFW):

One man who has two fully-functional penises goes by DiphallicDude (or DoubleDickDude, which morphed into DDD), as he is committed to keeping his real identity private. He is an American man in his mid-20s, living out on the East Coast. Beyond that, not much is known about who he really is.

About a year ago, he did an AMA on Reddit, that turned out to be one of the most popular of all time. He even submitted pictures as proof (obviously NSFW), if you’d like to see what diphallia actually looks like. When he said “Ask Me Anything,” Redditors did not hold back, dying to know what it is like living with that condition. It was revealed that DiphallicDude is bisexual, and has had sex with over 1000 people. While he didn’t go into too explicit of detail about his sexual experiences, he was able to confirm or deny most of the questions he was asked about the mechanics of everything.

His book is Double Header: My Life with Two Penises.

Over 1000 people and he is in his mid-20s? Hmmm… suppose he became sexually active at age 16 and is now 26, that is about 520 weeks. So he has had, on the average, about two new partners per week. That seems a little far-fetched.
