A man accepts a job in a village with no women

Once there, he asks a local:

-There are really no women here?

-None.

-So... What do you guys do when you need to have sex?

-There is a donkey close to the river for that.

The man tries to ignore that and goes home, from where he can see the river and therefore, the donkey. After months in that village, every day the donkey seems a little more attractive, so one day when a few other men ask him if he'd like to go to the donkey with them, he accepts. When he is close to the donkey, the man pulls down his pants and one of the other locals yells:

-What are you doing!?

-Aren't we...you know? Going to do the donkey thing?

-We going to ride the donkey across the river so we can get to the other village where we can meet women.
