The Man With Two Penises - Juan Baptista Dos Santos (NSFW)

Born in Portugal in 1843, Juan Baptista Dos Santos was born with two penises, three legs, and three scrotums. Probably most bizare is that everything worked- this wasn't some sort of mutant freak man with useless dangling appendages, but just a guy with a little extra of everything.
Well, that's not totally true. The leg didn't work- but it was so small and boneless that it could easily be concealed by strapping to one of his regular legs.
Everyone was far more interested in his multiplicity of male parts to pay any attention to that anyway.
What exactly Juan Baptista did with his life is not exactly clear. He refused to be a sideshow attraction- reportedly turning down several huge sums of money to appear in circuses around the world- but was very gracious with his time in medical circles and exhibiting himself to royalty and those with sufficient means.
The one photograph of him that remains was taken by a man named C. D. Fredericks, who wrote along with it :

"...the sight of a female is sufficient to excite his amorous propensities. He functionates with both of the penes, finishing with one, then continues with the other."

Here's the picture:

Strangely, Juan Baptista came of age and fame at the same time France was home to one Blanche Dumas, a courtesan with two vaginas. Everyone speculates that they had an affair when Baptista spent some time in Paris...I'd like to believe that happened.
I mean seriously, if you were either of them, how could you pass that up?
Probably the only two-person orgy in the history of the world.
