Lots of men have no idea what they are doing when performing oral... because women’s pussies are so different they really have no idea what pleases a woman or where to even start
Spot on.
My first girlfriend had a very sensitive clit. Any prolonged, direct stimulation would actually cause her discomfort. I figured out a way to work all around the clit, with occasional flicks of the tongue directly on it. That worked for her.
My last girlfriend was completely the opposite. You could lick, suck and (gently) bite her clit and she would go crazy...
