Getting Eaten Out Tonight

Ok so I think my man is gonna go down on me for the first time. Why I think that? He asked me to shave, and said that he wanted to try something tonight. And it's something we've never done before... I'm assuming he wants yo go down on me, and if that's the case... Any tips for getting a clean shave down there without any stubble and not tasting bad down there? I'm kind of nervous, and I don't want to be awful.
