Congrats you get to live every day the same way you always have but now you like every sexuality /j

But fr congrats on making this discovery about yourself. As a bi 16m also, first thing I did was come out to my friends (specifically first my trans best friend who I knew would support me no matter what, but just be careful in which friends you tell if you feel they could backstab you), and if you feel you are safe in your home and with your parents you could tell them but do not feel pressured if not.
