After his examination the doctor said to Biker John, a Police motorcyclist,

"You appear to be in good health. Do you have any medical concerns you would like to ask me about?"

"In fact, I do," Said John.

"After I have sex Im usually cold and chilly and then, after have sex with her the second time, I am usually hot and sweaty."

The Dr took notes.

The Doctors next patient was John's wife, for her check-up.

After examining her, the doctor said, "Everything appears to be fine. Do you have any medical concerns that you would like to discuss with me?"

She replied that she had no questions or concerns.

The doctor then said to her.

"John had an unusual concern, he claims that he is usually cold and chilly after having sex with you the first time, and then hot and sweaty after the second time. Do you know why?"

"Oh the crazy old fart."

She replied, "That's because the first time is usually in January and the second time is in August."
