Is it possible that your husband could go to a therapy session with you?

Sometimes people who have gone through traumatic situations tend to push their own needs aside or invalidate them. You have gone through a terrible experience and have every right to feel the way you do. If sex is still traumatic for you, I think this is something that needs to be discussed with your husband. Sacrifices are needed in relationships sometimes, but not to the extent that you are doing where you are essentially ignoring your own needs.

I hope this doesn't sound harsh, but I just think that your emotional well being is so much more important than his sexual pleasure.
