Is it weird?

so my boyfriend is my first but I’m not his. I️ know he’s been with other girls but I️ don’t really know exactly how many. I️ love him and I️ hope to be with him for the rest of my life but is that weird? The fact that he would be my only one and well I’m not his..? I️ try not to make much of it but I️ guess deep down I️ still think about it...
