NEED HELP!!

Emma
So i have this friend and him and i are planning on "doing things" i feel totally comfortable around him because he's a good friend and we've kissed and made out before. but i've never done anything more that that ever, (virgin) i want/ am ready to lose my virginity. but i feel like i should start birth control. is there a way to get it without my parents knowing? and how expensive is it? I feel like i should tell my mom so i could get it under her insurence, how do i tell her? what would she think? i don't need her to ask all these questions.
