In the Navy!

A young man joins the navy and is assigned to his first ship.
After a few weeks at sea away he starts to get really randy and eventually he can bear it no more.

In desperation he asks an old sea mate how he has managed through all his long years at sea.
The old sailor laughs and says "There is an old trick, come down to the canteen tonight and you'll see".

Later that night, the young sailor comes down to the canteen and sees half the ships crew in a long line behind a barrel.
One sailor is behind the barrel, his manhood inserted into a small hole in the barrel, and really giving it some.

Seeing the old sailor, the young lad asks " what's going on, this is not exactly what I had in mind, I mean shagging a barrel!"
"Don't knock it till you have tried it, its nearly a good as the real thing".

The young sailor is a bit sceptical but waits his turn and when it eventually comes,
can't actually believe just how realistic the barrel is.

Bouncing back to his old shipmate, with a big smile on his face,
he says "That was fantastic, just like you said, nearly as good as the real thing,
they should have more of these things".

"I am glad you feel like that way" replies the old mate,
"They have just done the draw and next week, its your turn in the barrel."
