sleeping over with boyfriend for the first time

So tomorrow night I'm sleeping over with the boyfriend for the first time. We've been talking for two years but couldn't be together because I was stupid and stuck in an abusive relationship. We've been together for a month and two weeks now officially. I've never slept over with any past boyfriends. He's coming over straight after work and staying with me until Sunday. We're going up camping with my parents Saturday night. I'm extremely nervous. 😩😳 Any advice or tips? Thank you 😊
