Jack and Jill.

Jack had a blind date with Jill for the prom and, as the evening progressed, he found himself more and more attracted to her.
After some really passionate embracing, he said.
"Tell me, do you object to making love?"
"That is something I have never done before," Jill replied.
"Never made love? You mean you are a virgin?" Jack was amazed.
"No, silly!" she giggled. "I've never objected!"
