ugh.... toughie toughie! i realized i was bi (more specifically pansexual) when i was 14. i didn't start dating until i was 16 and managed to establish relationships with males. i guess i never met my type of women and the ones i did meet were not interested in me

currently i'm dating a man so i haven't had to tell my parents yet... i know they would disprove.. my sister being very religious, dad publicly announcing if the church starts accepting gay marriages he will convert to islamic...
if you have a close relationship with your parents... then ok. you can probably disclose this information. but since you feel doubtful about it - i'd recommend if you feel the need for them to know, do it when you've moved out. that way, if they disprove, they won't torment you 24/7.
sorry i couldn't be of more help

good luck in figuring out what's best for you - either way i'm glad you are proud of who you are and are willing to express it to your loved ones.
