How to explain to him HOW to lick me out

Es

When he licks me out he sort of just dabs his tongue lightly in and out like he doesn’t really go for it.

But I think that’s because when he was licking me out once, he was touching my clit with his finger but roughly and my clit is so sensitive even I don’t touch it. So I just said “go softer” but I think he took that as all of it so now he doesn’t really go for it when he licks me out.

I’ve never come from oral so I’m not really sure how is best to do it or what will actually feel good.

How should I tell him to lick me out? Like what will feel good?
