Of the principals in “The Wizard of Oz”, who do you think would be most likely to have sex with Dorothy?
Answer: No one.
Why? Well, look at the Tin Man – no genitals, though fisting is a slim possibility.
The Scarecrow? Assuming he was constructed with a penis, a straw filled piece of burlap would be extremely rough and also not firm enough for satisfactory intercourse.
That leaves the Cowardly Lion, who was obviously a homosexual.
