Hello

I am using some else's account

I am 26 F in relation with a boy my age and I found that he has 10s of 1000s of screenshots and video grabs of not only porn stars but instagram models and actresses (downloaded from google search)

The latter 2 are in the higher quantity and I am worried.

He used to freely give his phone from the time we were dating but I never bothered to see what's inside. 1 year into the relationship I ended up getting into his phone gallery and saw the collection he has where the instagram screenshots itself are more than 20,000. When confronted about it, he apologized saying that this is what he considers normal and unless they are all 21+; he doesnt have an issue pleasuring over them. I was shocked, but in that state; he asked me if I intend to see a change in what he does; to which I refused to answer (He demonstrates change when he sees logical). A lot of them are regular people and not even influencers which made me feel odd. Its kinda odd, I dont think so lot of them are people that he even knows personally but there are 20,000+ of them. I dunno

Are there some boundaries that should I keep or make him keep? Is this what all boys do?
