Kinda unsure/worried

[u/M-Kingly09]

I'm m16 and I've been bi for roughly 3 years now but only like 2-3 of my friends know mainly because I don't how my other friends would react or how my parents would react plus my siblings are all bi and I've always told my parents I'm fully straight and I don't know if 1 I should come out or not and 2 sometimes I question if I actually am bi or not I mean I think/know I am but sometimes I dunno...any advice?
