LGBT+ Questioning?

i’m sexually attracted to girls, i know that for sure. i’m not scared of coming out because my friends and my brother know that i’ve been questioning (for about a month) and i know for sure i’m attracted to girls. i still like boys so i’m mainly questioning if i’m bi or not. i’m not opposed to having a relationship or kissing girls either but i just want to know that if i’m sexually (probably romantically) attracted to girls does that make me bi? i haven’t experimented yet but i don’t think i really need to at this point. any advice would be much appreciated :’)
