A man, known as Triple D, has been living with a very rare condition where a male is born with two penises.
Speaking to Newsbeat without revealing his identity, the 25-year-old from the east coast of America says his life would never ever be the same again if he allowed his identity to be revealed.
The man suffers from diphallia which is a rare condition where one-in-five million males in the world are born with it, according to a report by the BMJ, the global healthcare knowledge provider.
"If I wasn't going to have sex with you then you wouldn't know I had two penises. It's rare that anyone does know," he said.
Triple D said his parents had always told him that he was “special and unique,” and they had always advised him “not to play doctor with anyone else, don't take your pants off in front of other people."
He says he managed to keep his condition hidden from friends but when schoolmates found out in high school he went through a hard time.
Aged 16, he says he considered having one of his penises removed, but then abstained.
"I've always had these, this is my life. When I look down, what I see looks normal to me," he explained. He claims to have had more than 1,000 sexual partners.
"I wanted to do whatever I wanted to do with whoever I wanted to do it with - whoever would do it with me. There were situations where people would freak out."
Triple D describes himself as "very much bisexual" and has been in polyamorous relationships - sexual or romantic relationships that are not exclusive to one person.
Everyday things like buying underwear are an issue; he told Newsbeat he doesn't wear any.
Both penises are fully functioning. "I can urinate and ejaculate through both at the same time," he explains.
Triple D has self-published a book called “Double Header: My Life With Two Penises” in which he gives a full account of coping with diphallia.
