can I be bi

I'm 14 and for the past few years I have been struggling with my sexuality. I think I may be bi but I am not sure I have only told one other person about my thoughts and she kept wanting to talk about it which made me uncomfortable. I think I may be bi because I have an amazing boyfriend but I am also attracted to girls kind of as well as him I don't know what to think any advice??? I am also a virgin so that might be the cause
