Being Eaten Out for the First Time! Advice Needed

hey everyone, so tonight there’s a really big chance I’ll be eaten out for the first time! I’m excited but NERVOUS. I trust the person and all that but what if I taste or smell weird?! I’ve already shaved and gently cleaned my vagina with a wipe but is there anything else I should do? Or anything that I can do mentally so I don’t worry about those things? I would love ANY AND ALL advice on this subject!! Thank you!
