Reddit’s Ask Me Anything (AMA) section is one of the most unique functions the website offers where users can congregate to talk about, well, anything. When Reddit user “DoubleD**kDude” posted “I am the guy with two penises. AMA,” not surprisingly, the Internet came running for an explanation of this medical anomaly.

While the anonymous user kept his name out for obvious reasons, he did share that both are fully functioning and work independently from each other. Translation: both penises can achieve an erection and climax on their own.

“Both are 100 percent functional. It is Diphallia, not an absorbed twin,” he wrote in the post. “It's not genetic or inherited. I am bisexual and in a committed relationship with a man and a woman, but have permission to stray only with James Franco.”

That’s not to say he was free from any setbacks.

Reddit user 10ac: “Are there any possible complications you have to watch for?”

Reddit user DoubleD**kDude: “My prostate gets inflamed if I dont ejaculate enough. I'm probably the only guy with a legit reason to orgasm at least once every day or two days. My prostate gets stimulation from both cocks and creates a lot of seminal fluid. So when i cum it has to be squeezed every few days to get all the excess out. otherwise it feels bloated and painful.”

Diphallia, also known as penile duplication, may seem like it belongs in a science fiction novel, but health care professionals are well aware of this condition. Affecting one out of every five and a half million boys in the United States, diphallia is a rare medical condition with around 100 confirmed reports since Johannes Jacob Wecker discovered it back in 1609.

Experts are unsure of what causes diphallia, but speculate it occurs after the 23rd day of gestation following an injury, chemical stress, or a gene malfunction. Unfortunately, men born with this condition tend to die at an earlier age due to infections and renal failure.

Although both penises are able to function on their own, men with diphallia are usually sterile due to congenital defects. These men are also at a higher risk of developing spina bifida, a condition that results in malformation of the vertebrae designed to protect the spinal cord.
