My gf told me her past

I’m 24m and she’s 24f. She told me in the past she’s had sex with 3 different guys. One was her highschool boyfriend. One was a one night stand in college that she regrets and says she was drunk and the other was a situationship and that they hooked up 3x. I can’t really shake these out of my head at the moment. She did say these all happened in 2022 and hadn’t had sex since then until me in 2025. I know she isn’t promiscuous but I can’t overcome me comparing myself. I know she was younger and immature then, but her and I waited till we were official for sex and these other guys did not. Kind of hurts and I know I’m being ridiculous. Also her having more bodies upsets me a bit. I only have 1 and always assumed she had 1 aswell (I know dumb). Waiting for sex doesn’t bother me I love her for her, but one guy didn’t even wait a couple hours and the other they had sex on the first link. I know it was long ago and she’s changed since then but any input on the situation? I want to move on from it
