I WANT TO DATE A GIRL.

I'm a bisexual, more so leaning towards girls now. I have dated a lot of guys, but never felt really all that comfortable, and I've had a lot of crushes on girls, and been 'married' to one xD But I have been afraid to date a girl because my family are serious Christians and views gays as sick and mistakes that were created… if I were to one day be like "Hey, I got a girlfriend!" the likelihood of me being shunned by my family completely would be high. Like, my little sister saw a gay couple and went "Ew gross" in which I gave her hell for then got hell from my parents for thinking these 'things' are people …
There was a time I was talking to my friend Jordan , and was leaving the room to talk to him and my sister said "Talking to your boyfriend!?" And I almost turned around and said "He's not my boyfriend because I'M GAY!" but that would have been a bad way of coming out…
And my sister jokes with my about how I am so hopelessly straight! With men I will go "Oooo hello <3" but if I were to ever see a pretty woman no way would I ever say anything because I would be afraid of my families judgement, but apart of me wants to start showing them that I am kinda gay… so one day when I do say it it wont be such a surprise.. ugh, complications. I probably won't say it till I have moved out on my own. One of my best friends, Zack, he came out to his parents at 16 and was kicked out of his house, I supported and helped him, and he is much better now, living with people who care and having a wonderful boyfriend, but it was hard on him, and I don't want that for me. He came out to me in freshmen year, and I accepting, of course. All my friends know I'm gay, I came out to them all about 2 months ago, and most of them went "Yeah, we know." And was completely supported… now to get around to my family eventually. BUT HEY IF I COME HOME WITH A GIRL AT LEAST IT WON'T BE AS SUSPICIOUS AND WE CAN HANG OUT WITHOUT PEOPLE KEEPING AN EYE ON US
