You are starting the second year and I think that was the hardest. After DDay, I figured when I got to the one year marker that I would feel a lot better, but I didn't and it was very discouraging. I know the general wisdom is two to five years, but I just didn't want to accept that. I thought surely I would feel better in a year.
Year two was just as tough as year one for me. Actually but the third anniversary of DDay things were and are much better.
The sex thing could be because of shame, or that it triggers him, or that he really does not believe that you care about him. My husband also has that problem, and we have talked about it, but it sounds to me like it is mostly emotional for him. He also picked up a case of HPV from his darling girl, and now he is terrified that I might contract it.
Talk to him and you both probably need to talk to a counselor about that problem. You are very young and that problem will have to be resolved.
We are old folks (67) and I guess we can do without it. Very hard though when you are trying so hard to build your self-esteem back and want to feel that you are attractive to him. Hugs
