ANYONE PLEASE ANSWER! I need help telling my mom something?

So theres kinda two questions in one. So first my mom is VERY CHRISTIAN, and she doesn't like gays or anything, so how would I tell my mom that i'm bisexual?? and i also want to tell her that i'm dating someone, who is actually a guy. And she doesn't like when i date, she like even goes to the point where he cant touch me, i cant go on a date alone, or like anything. soo any help? i was hoping somehow i would be able to tell her about being bisexual then be like "on the bright side im dating a guy" kinda thing, i just don't want her to think something like "oh why would she be bisexual and date a guy when she was telling me?" like idk....i just want to tell her both things.....its confusing to explain, especially over the computer hahaha. PLEASE ANYONE ANSWER THIS! EVEN IF YOU'RE ONLY IS ABLE TO ANSWER ONE QUESTION PLEASE HELP! i need help!! IF YOU HAPPEN TO STUMBLE ACROSS THIS QUESTION PLEASE ANSER!!!
