Help!!!!

Okay so tonight my bf is coming over and he keeps telling me he's gonna eat me out. Well I'm a virgin and I've never done anything aside from kissing bc I wanted to wait for the right guy. He's the one. I know he is. Anyways, I'm worried I'll smell or taste bad. I'm all about hygiene and stuff so it's not like it don't clean myself and all that 😂 just worried something will go wrong. Any advice?? Or am I just worried about nothing??
