If he is such an ******* you don't need his approval anyway.
then why tell him? Wait until you are 18 and or out of the house. Just because you know doesn't mean you HAVE to tell.
wait until you are supporting yourself.
try cutting ease your way up son
Why does he need to know I'ts none of his business.
Come out bluntly. If he really loves you, he'll accept you, no matter what your sexuality is.
Tell him that you are his daughter and he should take you as you are. Just say I love you dad, but I'm tired of living a lie.
Hmm.... Maybe over dinner at your house?
WAIT TELL YOU MOVE OUT........ THEN NO ISSUES
