Going down

My boyfriend and I have safe sex and I rarely go down on him and he has been wanting to go down on me. But I’m nervous about what he’s going to say about it, like if it smells or taste weird or what if he doesn’t like my hair down there. Should I shave it all the first time he goes down on me or what should I do? Can I get any tips. We’re both new at this, we lost it to each other so we’re still trying to figure this out and trying to have fun with it.
