A man goes into see his doctor complaining of pain upon urination.
The doctor asks the man to whip down his tweeds and has a quick look at his old fella.
The doc then instructs the man to dress himself and take a seat.
The doc chews on his pen and says "hmmmmmm. Tell me do you masturbate a lot"
The man replies "yes" a little shyly
"Hmmmm" says the doctor again and pauses.
"Its great isn't it?!"
