Oh My God!

A big-city doctor visits an Indian tribe full of men, he asks

“How do you guys relieve your s*xual 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.”
