How often do you go to escorts?

[TonyB]

I remember a friend of mine telling me he visited the doctor.
He told the doctor he was living with a girl and every morning would have sex with her before work.
She went to work and he was slip in next door and have sex with the neighbours daughter.
Then he went to work and at 11 o'clock he would have sex with the tea lady who came around.
He met a girl for lunch nearly every day and they would fool around.
In the afternoon he usually went to an escort, before dropping in on his way home to his bit on the side.
His girlfriend was a little bit suspicious so every night she insisted on sex to ensure she was keeping him on side.

So you have sex in the morning, at 11, at lunch, in the afternoon, on your way home and at night.
Why are you here?, The doctor asked.

He replied it hurts when I wank...
