Is this totally natural and normal?

I have a friends with benefits. We declared what it is. We are very nice to each other. however, for the past couple of years, I’ve always wanted to friends with benefits after a relationship ended. I felt completely normal and OK with it because I knew I wouldn’t be able to deal with the stress that comes along with it anymore.

HOWEVER. My friends with benefits flirts in front of me with the other girls. I GET JEALOUS because I want all the attention on me and I get insecure when feeling like it’s going to end. Which, technically we are allowed it to End whenever. We don’t have each other on social media or anything because I don’t want to see what he is up to and that is not my business but when it’s in front of me, I get a little jealous and always feel some type of way. I guess because I don’t have anyone else like a second option. Is this normal?
