should I be worried?

So a while ago I noticed that my boyfriend follows some porn stars on instagram. Now he has Snapchat again and he follows some on there too. I kinda want to say that I don't like that he does but idk. What should I do? I mean I know he loves me and is attracted to me and that I'm just being insecure but just the fact that he does follow them bothers me. It just makes me wonder if he looks at them when he not with me ughh I hate this!! Help!😣
