birth control help

Katelyn
I've been with my boyfriend for almost 2 years and we've been having sex for almost a year now which we were each other's firsts. my parents are really strict about us like being alone and stuff. I think they know I'm sexually active, but I'm too afraid to admit to them and ask for birth control. we are always really careful when we do have sex and use a condom and pull out, but I still want to be on birth control! but I'm afraid if I ask i won't be able to go do things with boyfriend other than hang out in the living room of my house. what should I do?
