A big city doctor visits an Native American tribe full of men and he asks “How do you guys relieve your sexu@l tension?”
“Simple, just come down to the river tomorrow and we’ll show you.” The next day the doctor shows up and sees a group of men near a donkey. One man says “Since you’re our guest you get to go first.” The doctor not wanting to go against custom starts to kiss, then proceeds to have s*x with the donkey. Then a man in the group asks “Are you almost done Doc? We need the donkey to cross the river in order to get to the tribe of women.”
