A bloke goes to the doctor and says, "I got this sex problem, doc."
"Well," says the quack, "Tell me about your average day?"
"Well, 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 every day and we get a compartment to ourselves and have sex all the way there."
"Oh....now I see, "said the quack.
"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 quack.
"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?" asked the doc.
"Well...", said our hero, "it hurts when I masturbate."
