Told parents that I got birth control didn't go well.

My family is of oriental decent (not trying to be racist just cultures have different views) I'm born and raised in northern Virginia right outside of D.C. They ( my parents) first already wasn't happy that I had sex Now I'm 18 turning 19 in November 2016. I got the pill with my boyfriend (he's also turning 19) because we wanted to be responsible since we've been talking about it (we've been together for almost a year) My dad says don't take it (assuming he wants me to throw away the pills?)out of anger says he should get a gun a shoot all the guys and that we should wait til marriage and that its philosophy that's how things just goes. And that if we do it my boyfriend can't see me anymore. And that its disrespectful. I've been called stupid by my dad in the past and I've told him I don't like it and he says what I'm doing is stupid so I'm implying that he says taking birth control is stupid. This is how things normally goes in my household when it comes to serious topics like if I were to talk back. Or if I raise my voice cause they raise theirs at me sometimes. Or they say I don't do anything and I say my view and they just don't really acknowledge it or just say idk. Advice please.
