I was talking to a friend recently who has been married over 20 years. She is in her 50s. She said has not had sex for 10 years. Her DH seems not to mind and they have always seemed very happy together. I realise there is more than life than shagging, but I don't think I could go that long without DTD in a relationship. I could perhaps keep myself satisfied alone for a while but I would miss the cuddling and chatting afterwards, as much as the DTD part itself.
