What number comes next?

Sherry lost her husband almost four years ago and still hasn't gotten out of her mourning stage. Her daughter constantly urges her to get back into the dating world. Finally, Sherry says she'll go out, but doesn't know anyone.
Her daughter immediately replies, "Mama! I have someone for you to meet."
Well, it's an immediate hit. They really like one another and after dating for six weeks, he asks her to join him for a weekend in the mountains.
Their first night there, she undresses as he does. There she stands nude except for a pair of black lacy panties, he in his birthday suit.
Looking at her he asks, "Why the black panties?"
She replies, "My breasts you can fondle, my body is yours to explore, but down there I am still in mourning."
Obviously, he knows he's not getting lucky that night.
The following night the same scenario. She's standing there with the black panties on, and he is in his birthday suit...except... that he has a black prophylactic over his manhood.
She looks at him and asks, "What's with the...uh...black prophylactic?"
He replies, "I want to offer my deepest condolences."
