As a former "Navy brat" I know what you are speaking of. I can also be "happy" in whatever context I am in at the time because that was how I coped as a child. However, I have watched my Mom face a cancer dx and learn to state preferences as she NEVER had before and I have re-evaluated the importance of occupying your own space.
I AM a sexual being - whether or not my spouse notices or cares or not. I AM an attractive woman. I AM a caring spouse whether or not our sex life goes according to my preferences or not. I AM many things - frankly, some of them aren't so great. The point is that I am working on owning my sexuality in such a way as not to feel that I have to mask it or apologize for it. H can be part of it or not but I can still be sexy. The hard part is learning to HOM when he doesn't seem to notice or care.
