The middle-aged woman sought help from her doctor.

"All my husband does is complain that I never want to have sex with him.  And he's right too. I have no desire at all."

The doctor gave her a prescription and told her to return for a visit in two weeks.

After the two weeks were up, she bounced smiling into his office.

"Those pills were great Doc, I'm having  fantastic sex twice a night now."

"That's wonderful." said the doctor, "What does you husband say about it?"

"He don't say anything !" she replied. "I still don't have sex with him."
