Looking at other women

My boyfriend is constantly looking at other women. I think it’s totally normal to find other people attractive right. But like, he looks alllllll the time. And if a girl walks by he’ll pretend not to look thinking that’s what I notice but then he’ll find a way to turn around or something to look. It really is starting to bother me a lot. I don’t get compliments ever. But he has no problem looking at other women. Am I just being ridiculous? Be honest with me.
