I very much love my DW. Before we had our two children, we had a reasonable sex life, although I would always initiate. But since our children we have had very little sex (once every four months maybe) and nothing at all for now almost two years. My DW says that I am unreasonable in my 'needs' and that I should focus all my attentions on looking after the children. But I think it's destroying our marriage and I'm not prepared to sacrifice a sex life and frankly don't see why I should. I also don't think she fancies me. At all. Am I unreasonable? What should I do? I have 'got by' by using pornography in secret. I have also started fantasising about attractive colleagues, although I have never had an affair. The sexual frustration I feel is almost painful...Help?
