Two 90-year-olds had been dating for some time, when the man told the woman, "I think it's time we had sex, don't you agree?" The old woman agrees and the two make love that afternoon. Afterward, as they are lying in bed, the man thinks to himself, "My God, if I had known that she was a virgin, I would have been much more gentle!"
Meanwhile, the woman was thinking to herself, "My God, if I had known that the old geezer could really get it up, I would have taken off my pantyhose."
