I remember reading an article about Napoleon that said something to the effect that despite him being a dwarf, his cock was as big as Randy West's and his cumshots were as much as Jerry Butler's. I also remember reading that many of the women who worked with him were shocked that he was a better fuck than they thought a little person would be.
There is a sort of pornstar progression... When a woman first starts and looks young and innocent... The directors have her in lovey-dovey seduction scenes... After a while, the director figures audiences are getting bored with that... So it's "Let's have her suck to a messy facial".... Then it's two guys at once... Then three guys with a dp... Then it's gangbangs and blowbangs. And somewhere towards the end of the spectrum you end up sucking and fucking midgets. That does mean there were some very lucky midgets Mr. Short Stud had scenes with Angel Cash, Annie Sprinkle, Candida Royalle, Lisa Deleeuw, Misty Regan, and Seka just to name a few.
