14 and confused

So im a 14 year old girl but im confused about my sexuality. There's only 1 lesbian in my school who is out . And im not sure if im gay, straight or bi because ive not had any sexual relationships yet i mean ive had the odd boyfriend but i haven't done anything sexual with any of them. But I don't really care if im gay or not it's just that if girls come out as bi thats accepted because most guys at school find that hot but then the girls act really awkward around them but when any girl comes out as a full on lesbian everyone freaks out and call bullshit so they end up turning "bi" because everyone says that there are doing it for attention , and I don't want that but i do want to know what im into coz I don't want to spend my life dating guys if im into girls.

Any tips on what to do, or how to find out what im into???
