I’m so confused

So my mom said when I turn 13 I could start dating and now I’m 14 and I liked boys for a period of time until I really started to notice girls but I didn’t think it was real until this girl that is my friend started to flirt with me and I actually liked it I didn’t think I would but my body reacted to it in a weird way and this has been going on for days and I have a boyfriend I’m so confused I think I am bisexual...should I be...I need advice
