Okay, so in Febuary my ex boyfriend and I had sex, it was protected, we were together for 9 months, but I didn't want to have sex with him, he kept asking and kept asking so I finally said whatever, I had turned thirteen in January, well I wanna ask my mother if I can start using birth control, but I don't intend on having sex again, I would just rather be safe if I do give in to someone again. How do I ask her without making her think that I plan on or I am having sex?
