Boyfriend looking at underage naked pictures

i'm a 22yr female my boyfriend is 21. I found out that he's been looking at 14yr old naked pictures and i don't know exactly what to do. I confronted him about it and he says he likes to look at younger girls rather than older girls. is this quite serious or quite harmless??

Um... i don't think that enjoying to look at naked underaged girls is very normal. If i were you i would talk to him more about it... somthin like that could be harmless but it could be serious too so i'd rather be safe than sorry. ~Sam
