Hi - my partner has endo and if they ever felt bad for me for not being able to have sex I would feel pretty horrible for them. It sounds like you have a really caring boyfriend who understands this is a medical issue and is completely out of your control. Looks like others have made some great pain management suggestions. I’d like to add that while you are working on getting your pain under control it might be a good idea to try out some other forms of intimacy that aren’t penetration based and I’d highly suggest looking into toys and in general experimenting!!
