An elderly man and woman meet in a bar and get to talking.
They are enjoying their conversation so much that, when the bar closes,they decide to continue at the woman's apartment.
After a time, things start getting pretty romantic and they wind up
in bed. Afterward, they're both laying there, staring at the ceiling.

The old man is thinking…
“Gosh, if I had known she was a virgin, I would have been more careful with her.”

The old lady is thinkin…
“Geez, if I had known he could get it up, I would have taken off my panties.”
