"Vagina-Wise" joke

There were three men of different nationalities who were discussing about their conquests of women. They started to define the female organ:

One Said:" It is very exclusive. Why?' Cos only one can get entry ata time."
Another said:"It's a very holy thing. Why?' Cos only the upright and the righteous can enter"
The other said:" It's like a bank. Why?' Cos once you withdraw you lose interest!
