insecure over my bf's porn searches

Like most girls I like to go snooping through my boyfriends phone, especially his search history on the internet. He watches videos featuring "big tits" and "anal" and "titty fucked" which makes me feel SO insecure because I'm smaller chested and I never do anal. Are these fantasies he has that I can't provide for him? Should I say something about it? Should I even let it bother me? 😩😩
