Advice on oral sex?

Mira • Carribean is My 🏠| 16

So I have a boyfriend and we’ve been together for a while and I was wondering about him eating me out. We have talked about it and he wants to do it but I’m nervous, what if it smells or taste weird. It would happen at the end of the day and I’d rather it happen when I get out the shower and I’m fresh personally but that’s not realistic right now. I’m wondering if someone can tell me some advice on what I should do?
