How do I tell him?

How do I tell my boyfriend that I’m craving girls? He knows that I’m bisexual and thought it was a huge turn on, but lately that’s all I can think about. I’ve never really had the chance to experience in that kind of field. Just to clarify, I’m talking about making out not being intimate with anyone else but him. I love my boyfriend more than anything and I’m afraid that he might not like that idea, which would be totally justified and I could live with. How do I bring this up? Has anyone else been there? Please leave me your honest advice and story times down below ☺️
