How to ask for birth control.

So I’m 17 and I just recently lost my v-card. We used a condom but honestly, it’s sucks.

So I want birth control now. But I don’t know how to ask for something like that.

Here is my situation.

I’m dating secretly

I come from a military family

I don’t really get to leave the house that much

But I really love this guy. I trust him.

And I really don’t want to end up pregnant cause we are both freaking little teens and I can slowly feel my concern but him going in raw starting to fade.

Please I just need some advice, experience, on how to ask for birth control from strict parents
