"The Astonished Physician" joke

A beautiful but obviously overwrought young woman tearfully admitted to her doctor that after almost a year of marriage, her husband had not yet made love to her.
"No wonder you're nervous and upset,". said the astonished physician. "Bring your husband to my office tomorrow afternoon and I'll have a talk with him."
The following day, she returned with her husband.
"I dislike prying into your personal life, my good man," the doctor said, "But you're not fulfilling your marital obligations."
"What do you mean, doctor?" the naive husband replied. "I'm considerate, gentle, devoted and a good provider."
"But what about your sexual obligations?" the doctor demanded.
"I don't understand," the husband replied.
The doctor tried to explain, but the husband was too stupid to comprehend.
"All right," said the doctor at last, in exasperation, "then I'll show you."
He then asked the pretty wife to disrobe. After she had wriggled out of her clothes, the good medic proceeded to make passionate love to her. When he was finished, the doctor said "And that's what every married woman needs at least twice a week."
Seeing the happy glow on his wife's face, the husband could only agree. "Very well, doctor," he said, "we'll be back on Friday for another treatment."
