It takes a lot to have a relationship that includes others intimately. Not many people can handle this type of relationship but for those that can it can be a very fulfilling lifestyle. A situation was brought up that can evolve by one partner having to become celibate. This happened to us. Well over 40 years together and her body failed her years ago. She cannot have sex anymore. But I can and do have those feelings of desire for sex. There is a good read by Dossie Easton and Janet Hardy "The Ethical Slut". Both of these women have experienced open relationships and failed. Both now succeed within their relationships while having other partners intimately. Taking suggestions from the book my spouse and I worked out details that allows me to satisfy my desires to continue sexual relations with a woman. This path doesn't weaken the true love we have for each other but has strengthened it.
