It's best not to start talking about getting intimate again when you are in bed. Doing this can put a lot of pressure on the conversation. Do it on one of those better days, when you haven't had any doctor's appointments or difficult situations to manage and have less pain. Of course, it is difficult to plan when that will come together. It can be liberating for both concerned to talk about their fears, their frustration, their emotions. You might find that once you have found the courage to raise the subject, your partner doesn't want to talk about it. Just starting the conversation with your partner by saying that the symptoms of fibromyalgia make it difficult and you would like their help in finding a way to become intimate that is doable for both, could be an example for a door opener.
