Sex, Women, Husband & Doctor

A woman who had the worst chronic headache goes to a famous "new age" 
 holistic doctor, as a last resort. 
 
 "Doctor, I have tried everything, but my headache just won't go away." 
  
 "You have come to the right place. 
 
 This is what I want you to do: go home, stare at yourself in the 
 mirror,  point your index fingers at your temples, and repeat this mantra: "I 
 really don't have a headache, I really don't have a headache". Do it as 
 long as it takes, the headache is just going to vanish." 
 
 As she leaves the doctor's office, skeptical but curious at the same 
 time, she tries the maneuver in front of a mirror a headache, I really don't have a headache..." 
 
 She has barely said it four times, when she realizes her headache is 
 gone. Shocked and elated, she runs back up to the doctor. 
 
 "Doctor, you are a genius! Can I please send you my husband? He's been 
 having problems in a certain department... how can I put it... " 
 
 "When was the last time you two had sex?" 
 
 "About eight years ago." 
 
 "Send him over." 
 
 A few days later, she is waiting with baited breath for her husband to 
 come home from the doctor. He arrives, asks her to wait, and goes 
straight  to the bathroom. When he comes out, he throws her on the couch and 
starts  making love to her, wildly. When he's finished, he goes right back to 
the  bathroom. A few minutes later he comes out, rouses her from her bliss 
and  starts at it again, like an insatiable young man. After another hour of 
 great sex he goes and locks himself in the bathroom again. 
 
 At this point the wife has become unbearably curious. She tiptoes to 
the  bathroom door, looks through the keyhole, and sees her husband, staring 
 at himself in the mirror, fingers pointed at his temples, 
 repeating: "That woman is not my wife, that woman is not my wife.....
