i’m bisexual myself,, so just wait a bit for signs that show whether your parents are supportive of the community or not. if they are,, wait until you have enough confidence to tell them. if they aren’t, wait until you move out ( i don’t know how old you are), then tell them so you don’t get kicked out or anything like that (i’m sorry if this sounded like i was trying to scare you). i hope this helped
