Head tips

My and my bf have been dating for 3 months now and we’re long distance but we make frequent trips to see each other, I’m planning on seeing him for my birthday and he had mentioned to me before that he loves giving head, I’ve never received head before. Is there something I should do?? I’m like so nervous bc I don’t want to “taste bad” I mean it’s a organ so obviously it’s not gonna taste amazing but I’m scared 😭 no one wants to be the one girl their bf has been with who tastes bad.
