First let me explain how the sex machine came to be When Rob and I first met I was only just nineteen and he was already thirty-six, nearly thirty-seven. People used to look at us and think he was my father because I am quite small and slim I look even younger than I am. I found this quite amusing, especially when we kissed in public and I saw the looks on their faces! By the time we married he was nearly forty. In the early stages of us getting together we would make love all the time but as things settled down it became less and less frequent. I know that I was more highly sexed than he was and I started to get frustrated and resentful when he wasn't in the mood.
