Is that reason good enough to leave my boyfriend?

Hello
Me and my boyfriend agreed to only have sex after marriage but he follows more than 4000 girls with bikinis or nudes on IG and Facebook
Sometimes he likes these photos too

the girls are random girls most of the times but there are some of his colleagues even girls he only met once

he is very kind and sweet and honestly I love him I said to myself as an excuse it’s probably because he is still a Virgin , probably thirsty.. etc but I am terrified that this will multiply after marriage not decreasing

1 - is that a good reason to leave him and say no to him?
2- will i be ever enough for him with all of my imperfections? I mean after seeing 4K girls I don’t look anything like them most of these photos aren’t real they are edited especially on IG
3- should I confront him that I know about it or is it a useless step?

i would like to hear the answers from men more as a trial to possibly understand how he my boyfriend thinks when he does it

Is that reason good enough to leave my boyfriend?
