I want to have sex

My boyfriend wants to have sex and I want to too but we can't find q place to do it. We're only 13 so we don't drive yet so idk where we can go. Also I don't want to get pregnant so how long can be stay inside me. And my boyfriend does want a baby but I think I want to wait until next year so we can get jobs to pay for the baby 
You all don't have to be mean. And I hope you don't ever have children if you think it's okay to beat them. At least I wouldn't abuse my baby
