I once had a girlfriend who was learning to drive when I met her. So she passed her test and the day after she took me out in her new car. We drove into a car park and the only space left involved a fairly tight reverse to get into it.
She said, "Oh my God, I'm not sure I can do this, I hate reversing".
So I said, "Look darling, I'm sure you'll be fine. Just do exactly what you did when the examiner asked you to reverse round a corner yesterday".
So she lent across the seat and undid my trousers...
