Missing Something

A man was lying in bed with his new girlfriend. After having great sex, she spent the next hour gently scratching and massaging his balls She was so meticulous about it and it was obvious that this was something she loved to do.

The man was thoroughly enjoying it but he was curious about her fascination. He turned and asked her, “Why do you love doing that so much?”

”Because,” she replied, “I really miss mine.”
