A bloke went to the doctor and said, "I got this sex problem, doc." "Tell me about your average day," said the doctor. "It all starts in the middle of the night. My wife always wakes me up about 3:00 am for nookie and then again about 5 o'clock so we can spend a couple of hours making love before I go to work."
"Oh I see," said the doc. "No, hang on." said the man, "You see, when I get on the train to work I meet this girl everyday and we get a compartment to ourselves and have sex all the way there."
"Oh...now I see," said the doctor. "No you don't," said our hero. "When I get to work my secretary really fancies me and I have to give her one in the storeroom."
"Oh...now I see," said the doctor. "No no no," he said. "When I go to lunch I meet this dinner lady I'm very fond of and we nip out the back for a quickie."
"Now I understand," said the patient doctor. "No, hang on," said the bloke. "When I get back to work in the afternoon my boss, a very demanding lady I might add, has to have me or she says she'll give me the sack."
"Ahh..." said the doctor, "now I see." "No, there's more." said our man, "When I get home my wife is so pleased to see me she gives me a blow job before dinner and then we have sex afterwards."
"What's your problem then?" asked the doctor. "Well..." said our hero, "it hurts when I masturbate."
