A carburetor walks into a bar…

So a man is not getting a lot of s*x from his wife. So he goes to a s*x therapist and he tells him about his problem. The therapist tells him the next time you want s*x from your wife just tell her you want to use her washing machine. The man thought that this was strange but at this point he was willing to try anything.
He goes home and when they went to bed that night he looks at his wife and asks her if he can you her washing machine. His wife immediately complies and they have great s*x night after night for the next couple of weeks until one night when she was just too tired and try as he might he just didn't have any luck.
His wife started feeling guilty and later that night woke him up and told him that he could use her washing machine to which he replied,........ oh that's okay honey, it was a small load, I did it by hand.
