Are you ok with your boyfriend saving photos of naked girls on his phone?

Back story to question:

My boyfriends friend sent him a naked photo of a girl he hooked up with and my boyfriend saved the photo (on Snapchat not his actual phone) & I accidentally seen it and said I was uncomfortable with the idea of him saving this photo as 1 I don’t think it’s right to have naked photos of other girls while you’re in a relationship (personal opinion) and 2 it is very disrespectful of his friend to send a photo like this as neither my boyfriend nor I are sure if she knew the photo was sent...

My boyfriend agreed and said he never thought it was bad because he doesn’t know the girl and will never meet her (his friend lives 20+ hours from us) / had no intentions on using the photo for self pleasure.. said he saved it just because he found her cute.. he said he never took in consideration that the girl in the photo may not be aware her photo is being sent around.. so he unsaved the photo and now views the situation as bad and has apologized for even saving the photo in the first place... but I still feel slightly hurt..

Feel free to comment how you would feel.. I’m just curious
