first time help

okay so there’s this guy who I flirt with a lot and we’ve both talked about having sex before and possibly soon. i’m 17 and still a virgin, which I have no problem being so let me clear that up. i’ve never had sex before and the most that’s happened to me is fingering. i know i’m ready for it, i’m just nervous. is there any tips on how to settle nerves or any other tips?
