cummin in me

We've been best friends since 6th grade and have been dating for a while I have my own house but he hasn't moved in yet but we talk about it but he asks to cum in me and I said yeah we are stable to have a kid and I don't mind if we do but after he did he was joking about us having a kid but we both joke about it all the time about having a baby but I don't know if this is a sign that he really does want to have a kid I asked him if he's worried about me getting pregnant that I'll get the plan B but he says he ain't worried like he acted normal about it also I'm not on birth control
