I (21M) found nudes and other things of my gf (19F) sent to me and other exes. and i dont know how to deal with it

I (21M) and my gf (19F) have been together for 1 year and its been through online and we plan to meet soon one day. over the course of our 1 year together i think ive learned a lot about her past that maybe i didnt need to know. shes my first but im not hers. i learned about all the abuse and other stuff shes endured and im happy she could feel comfortable and get it all out with me. but with hearing that i heard about a lot of sexual experiences and stuff like that. and recently we went thru each others social media accs, old ones. and while going thru i knew wat i was going to find but i still went thru and clicked anyways. it was 100% self destructive and i dont know y i did it. but i found old nudes, videos, and msgs sent to exes, stuff like that. and even nudes sent to me that have been sent to them. we had a talk about it afterwards and ik why they were sent back then, they were sent out of fear and shes been thru a lot of abuse too. And ik its wrong to feel this way about the whole thing becuz you shouldnt judge on a persons past and i thot i got over it long ago. but seeing it with my own 2 eyes did sumthign to me to where i cant even be in call with her rn or do anything sexual. i lardy deleted off my phone the nudes that she sent to me and them, because even tho i dont need to, i just cant look at them. ik this is silly that it feels less special and im not supposed to look at it like that. but i cant help but feel that way.

how do i get over this? i thought ive been over this because i learned all about the details about a lot of things over time, but actually seeing it is a different story.

tl;dr
i cant get over seeing nudes and other flirty msgs and videos that my partner has sent me and other exes. it makes me feel less special especially since im not her first and shes mine but ik its silly but cant shake the feeling still
