A young couple were married, and celebrated their first night
together, doing what newlyweds do, time and time again, all
night long. Morning comes and the groom goes into the bathroom but finds no towel when he emerges from the shower.
He asks the bride to please bring one from the bedroom. When she gets to the bathroom door, he opened the door, exposing his body for the first time to his bride where she sees all of him well.
Her eyes went up and down and at about midway, they stopped and stared, and she asked shyly, "What's that?", pointing to a small part of his anatomy.
He, also being shy, thought for a minute and then said, "Well,
that's what we had so much fun with last night."
And she, in amazement, asked, "Is that all we have left?"
