A young couple had recently gotten married, and after three months, the wife went to the doctor for a check-up. The doctor told her she was pregnant. She was thrilled, but the doctor also informed her that, due to a rare complication, she shouldn't have sex with her husband until after the birth.
The wife went home and told her husband what the doctor had said. The husband agreed to try and hold out.
After a month, the husband couldn't resist anymore and asked his wife to be intimate. Of course, she refused. Seeing her husband so depressed and sad, the wife called him over and said, "My dear husband, I know you're suffering. Here, take $100 and go to a sex worker to relieve yourself."
The husband took the money and thought to himself, "What a wonderful and considerate wife," opened the door, and went down the stairs, feeling cheerful.
When he reached the first floor, the neighbor's wife saw him and asked, "Why are you so happy?"
He happily told her the whole story.
She then said, "Why go looking outside for a sex worker? Give me the 100 bucks, and I'll take care of you."
The man agreed, gave her the money, went into her apartment, enjoyed himself for twenty minutes, and then returned home.
His wife saw him and was astonished, asking, "What happened, dear? You came back so quickly; did you change your mind?"
The husband replied, "I went downstairs, and the neighbor saw me. She offered to take the money instead, so that's what I did."
His wife got very angry and said, "What a jerk! When she was pregnant, I did her husband for free!"
