Dizzy

`Doctor, I`ve got this problem,` a 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 everyday at lunchtime 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...`
