Should I be jealous?

Ma

Boyfriend came back from camp. He showed the pictures that he took and I saw that a couple or three girls took a picture with him riding on his back. In some pictures, he was carrying them like newlywed style. I felt a little uncomfortable and it’s starting to bother me and more. He has never even carried me like that but has taken pictures with girls he knew from camp carrying them. What bothers me is the fact that he can get that close to other girls. I don’t want it to be bother me. How should I see this? 😓 maybe I’m overthinking it.
