bfs porn search history worries me

Im totally fine with my bf watching porn, I do it too. porn isn't my problem... it's what he's searching that has me weirded out. he is 36 and he has been searching "super tiny teen" "super sexy teen" "tiny girls" etc I clicked on some of these links to see and the girls are probably of legal age but they look young asf (13-16) and they are all super small stature. that part creeps me out. teen is a pretty popular search topic but the fact that he goes as far to search "tiny" really weird me out! please tell me I'm overreacting. I feel sick to my stomach.
