How do i tell my religious dad i'm a ?

i am a fifteen year old girl and i am a and there's this girl at the resturant i always go to and i think she is sssooo hot, but i can't tell my dad because he is really religious and he won't except it. i have even asked him how he fells about ity and he said he hates them. i am worried he would hate me but i can't help who i am and what i feel. so how should i break it ti him.
