I want to be a boy, but I’m not transgender?

So I’m 20, and for the past few years I’ve kinda secretly wanted to be a boy in the most basic sense. I want to cut my hair, wear masculine clothes, go by a male name, and even be referred to as a man. This is all a bit weird for me as I’ve always been super feminine and dainty, and I definitely don’t experience gender dysphoria. I really love being a girl, it’s just that there’s this really quiet voice in the back of my mind saying it wants to be a boy, and that being one would make me feel more comfortable. It’s no longer become a passing thought or a what if, its become more intense. I don’t really know what this is, and basically I’m wondering if it’s normal or if there’s an explanation? I’d love any and all advice I can get, thank you!
