How exactly does "going down on a woman" work? Is it just licking. I heard a good strategy is to write out the letters of the alphabet with your tongue in her puss
I will answer your question seriously though:
Its licking with varying speed and pressure, on the clit, around the clit, everywhere really. And not always just a 'licking' motion like you would lick an ice lolly, but moving your tongue side to side, up and down etc.
I can't imagine the alphabet thing working for me and it just sounds distinguished mentally-challenged really, especially if you're doing it with your tongue IN her pussy
So there is no conclusive way to lick pussy, every girl likes different things.
