Hyper sexual after D Day

DDay was about 2 months ago. Immediately after I felt incredibly shut off to the idea of any type of sexual activity with my boyfriend. Since I lost all trust, and lost a lot of self-esteem, i lost all of my sex drive as a result. He is now in recovery (which he chose to do) and we are in couples therapy as well as individual therapy. It has only been two months so the betrayal shock and trust issues have not been worked through yet. However, recently it’s felt like a switch flipped in me and all of the sudden I’m hyper sexual. I feel like I want it all the time. I don’t know why this has happened suddenly, and it feels wrong, like I shouldn’t feel this way. Has anyone else experienced this? I can’t seem to make sense of it.
