honestly ... don't do it. When you're so young sex really isn't all it's cracked up to be. I mean, if you don't use contraception or it fails if you do use it, are you capable of supporting a baby? And besides how long have you been with this guy? Do you trust him? Are you sure that he isn't going to leave you as soon as he gets what he wants. I'm not trying to be harsh but don't be so easy! Make him wait, if he really likes you then he will wait till it's legal .
