A middle aged businessman goes to see his physician. "Doctor, I've got this problem," the man says. "My secretary, she loves to give blow jobs. Every morning when I get to work I get a blow job. She gives me a quick one before I leave for lunch. And before I leave work at the end of the day she really works me over."
"So what seems to be the problem?" the doctor asked.
"Well, you see, my wife is a nymphomaniac," the man continued. "I service her every morning when we get up. I go home for a quick half hour every day at lunch and then we have a marathon session each night before we go to sleep."
"I still don't know what your problem is," said the doctor.
"You see Doc, every time I masturbate I get these dizzy spells."
