There is one porn actor who made a couple of straight films for the New York-style MAFIA-supported film porn industry. He was a Texan. Not much to look at. His penises were one above the other, about six-inches or less. He had two complete sets of testes, two prostates, etc. And oddly enough he appeared to be circumcised! He costarred with Jaime Gillis in a couple of films and then disappeared (probably sleeping with the fishes). Maybe he found Jeebus and is now a sunbeam for him. Who knows?
His forte was being able to do vaginal and anal at the same time on a woman. He also ejaculated at different times rather from both penises at the same time. You may be able to find him in collections of the old Wet Brothers films.
But the guy did, in fact, really exist. Somewhere locked up in my fire safe in Nevada I've got those two tapes. In one of them there's a serious amount of time spent with the women (and his male) costars exploring his goods (yanking, pulling, twisting, etc.) so it's rather obvious he isn't wearing something prepared in silicone and glued on. He also spends a great deal of time "crossing swords" with Gillis' dick sandwiched between his.
If Gillis is still alive, I'm sure he could be sought out and confirm the rumors. After all, he appeared in both films with the guy.
