my bf gots a list of girls he had sex with

my boyfriend and i been on and off but talking for two-three years and we decided to just be in a serious relationship & official dated in aug 2020. i’m pretty serious about him & we was good friends since 2017. i know him from the back of my hand & i don’t really go through his phone because i trust him completely & I KNOW he will never cheat or talk or flirt with any girl. but today i decided to check his notes and i found a list of girls be had sex with in the past, my name is on there too & i honestly DONT know how to feel about it. normally i’m a chill girlfriend & i just honestly don’t know how to feel bout it. we are both adults but this just caught me off guard. i don’t know if i should bring it up or its normal for guys to have it.

it did upset but i don’t know if i should bring it up
