This is really insightful, especially with a previous relationship of mine where I lost libido. I found that my ex-partner had a very strong and aggressive libido, while mine was more delicate and sensitive to his more demanding desires. Ultimately I wound up leaving him because he was simply too demanding, and I felt scared and guilty, tying him to someone who would never make him fully happy in the sense that he needed. We had talked it over, and he admitted that he wouldn't be able to be happy in a sexless relationship, that it was a main part of his life, and he couldn't bear to be happy without it.

And now, I'm faced with the same issue, but my current partner is much more understanding and delicate about the situation. He doesn't guilt me intentionally or unintentionally about my sudden drops in moods or my struggles with being touched wrong. He doesn't take it personally (I hope) when I tell him I'm not in the mood. It makes it easier, it makes me feel safer, and it gives me hope that all is not lost between us.

Also, PandorasAquarium, if the issue now is with his stamina, there are ways to help bring that back up! But I'm not sure if the stamina is what you would need, considering the possibility of pain. Definitely look into those options though
