Help!? ....fingering...eating out...

Okay so I'm meeting my S/O today, we're going to his house and he has a free one...Now whilst we've been dirty  texting and all that..he's told me how much he wants to eat me out and finger me. Now I'm really nervous because it'll be the first time he's ever done it to me... What I'm asking is how do I make it not awkward? What if I can't cum? ( I've never orgasmed before) I don't wanna make him feel bad because I can't cum...??
