Mary And John Are Both Living In A Big Apartment-house In New York City

One day they meet and instantly fall in love with each other, but they don't make any contact.

This goes on for six months until John just can't bear the tension any more and asks her to come to his apartment for a drink.

Hesitatingly she says yes and as soon as they reach his flat they close the door behind them and rush into the bedroom and throw themselves on the bed.

After a few minutes John explains with a hoarse voice, "Listen, I am very sorry, but if I had known that you were a virgin I would have taken more time."

Mary replies, "Well, if I had known that you had more time, I would have taken my pants off!"
