"What do men do for sex then?" asked the soldier
"Desperate men use the camel tied up in the village square" said the sergeant. Disgusted the soldier walked off back to the fort.
This went on every leave visit to the town for 2 years. "The nearest women are 100 miles away in Siddi bel Abbis. - desperate men use the camel tied up in the square".
Finally the soldier is so randy he overcomes his disgust, waits till the dead of night and sneaks up on the camel tied up in the square.
As he has his way with it the camel goes berserk, squealing and bucking and trying to bite but he hangs on till he has got his rocks off - by which time a huge crowd has gathered in the square pointing and laughing.
The soldier spots the sergeant in the crowd and goes over to him asking "What's all the fuss about - for two years you have told be that men desperate for sex use the camel tied up in the square?".
"Quite true" said the sergeant "but all the others used it to ride 100 miles across the burning sands to Siddi bel Abbis!"
