What should I do?

I have known that i liked females as well as boys since I’ve been in middle school. i was questioning my sexuality since then so i didn’t exactly put a label on myself. once i got in high school and started to understand things better i known that I am bisexual but i am more attracted to females than guys but still consider myself to be bisexual. I am 17 and don’t know how to tell my parents that i am bisexual as well as other members of my family without them judging me and looking at me different. what should i do? need advice.
