Her Sexual Problem

A woman went to her psychiatrist because she was having severe problems with her sex life.
The psychiatrist asked her many questions but did not seem to be getting a clear picture of her problems. Finally he asked, "Do you ever watch your husband's face while you are having sex?"
"Well, yes, I did once," the woman replied.
"Well, how did he look?" coaxed the psychiatrist.
"Very angry," she answered.
At this point the psychiatrist felt that he was really getting somewhere and he said, "Well, that's very interesting, we must look into this further. Now, you say that you have only seen your husband's face once during sex; that seems somewhat unusual. Tell me, how did it occur that you saw his face that time?"
"He was outside, looking through the window at us."
