first dick appointment advice?

this guy is gonna come over to my apartment and we’ve both made it clear that we’re going to have sex but i’m super nervous and i’m a awkward person in general. i feel like i’m gonna scare him off when it comes down to him coming over. like i don’t know what to say when he comes through the door or how i should even start. please need some advice

edit: it’s gonna be pretty early in the morning so that’s also something to keep in mind. i kinda just get to it. but he said he can stay a bit so we can just hang out and idk how i feel about that cause i’m pretty shy
