I knew she was a virgin

Two 90-year-olds had been dating for a while, when the man told the woman, “Well, tonight’s the night we have sex!”

And so they did.

As they are lying in bed afterward, the man thinks to himself: My God, if I knew she was a virgin, I would have been much more gentle with her!

And the woman was thinking to herself: My God, if I knew the old geezer could actually get it up, I would have taken off my panty hose!
