SOS: oral help needed stat!

Alright ladies, here's a challenge for y'all. I'm with a new partner recently who's never given oral to a woman, but he's open to trying it out. I have also personally never received satisfying oral, although I know my own anatomy relatively well. As such, I'm not sure how to tell him what to do! What are some pointers I can give him so that we both have a good time?
