Let me say that every woman is different. You just have to try different things and watch for her reaction and listen to her moans and groans.
Personally for me, I prefer being licked around my clit to start off. I like the feeling of the tongue licking the whole length of my vagina, from top to bottom and to top again. Probing deep inside is great too. I also like seeing his whole face covered in wetness and watching him enjoy it too. When I am about to cum is when I like my clit licked...and not just with a tip of the tongue either, I want him to lick it as if he's licking an ice cream cone. I am vocal so there's really no guessing game for me. I would let your woman know that you want to know what makes her feel good so let her tell you.
