Is our sex life changed forever?

My husband and I have always been kinky and passionate in bed. We always explored things and he would moan my name so loud. 2 years ago he went through something bad. We were on a break and he had sex with someone but realized it was a mistake and said he wanted to stop and this person got ad and held him down (He's short 5'4, I"m 6'2) and violated him in a very traumatic place. Legal actions were taken and she got 9 months. Since he's very quiet during sex ad mainly does missionary. We talked a little about it in marriage counseling and he just said he felt weak before but even more now. I don't know why he felt week before but he wanted to change the subject. Just seems like our sex life is going down hill.

Edit: My edit was abosultely horrible. It was out of frustration and that's not an excuse...
