Got back together with my ex do I have to tell him what I did when I was single? ?

got back together with my ex. We broke up in may. I got together with many (toxic) guys after that and I just became rlly sexually open to the idea of everything. Got really good with sending nudes and sexting like soooo good. My ex was my first kiss/oral etc. I was his first too. Never went all the way with him or anyone. But Im like 99 percent sure he talked to no girls after me bc he was heartbroken. And here I am messing around with 5 guys.
