SSM- give me a link to your story...I have a couple of "what I would have done's" as the "LDS" but it may not be applicable. In my case if H had sat down and said I cannot live this way, let's (notice not me alone) but let us both get some help with this, or I am done, I might have listened. Can't guarantee, because a lot of things, not just the sex, would have had to change.
By no means am I actually low desire at all, I am finding out lol!! It was just tied into so many things in my marriage that I could not extricate my physical desire for H from all the emotional baggage I was carrying. His fault? Not entirely, but not entirely mine either.
Maybe for some women wanting physically is enough to have sex whenever, wherever, with H, but I realize, not for me. That is a huge revelation, but one I unfortunately did not come to in my marriage and therefore could not say to H "It's not that I don't desire you, it's that I need this fulfilled first. It's no good having sex and then feeling just as lonely and unfulfilled afterwards..at least for me
