Lewd Cosplayers

I opened my boyfriend's instagram to show him a meme I had sent him. The first thing that popped up was a girl making a lewd face that's popular now. I looked through who he's following on this account and the majority are lewd cosplayers or barely legal girls. He's only 19, but its still weird. They are all small, skinny, and white. Which I'm not so I'm concerned.

This kind of happened before when he came home after helping his parents for four months. His explore was filled with almost naked women. I just don't know how to start a conversation about this with him. It definitely bothers me a lot.
