I don't mean to sound like I'm jumping all over this comment, frostypeaches. But I have known one girl who HATED being fingered, whether being licked or not. But she loved oral sex, otherwise. What would rock your world was just uncomfortable for her.
There are very few truly universally appreciated oral sex techniques.
While I agree with that last statement I want to point out that fingering is something that
I believe the vast majority of men are shite at. This is, of course, as a result of my own experience. I actively discouraged fingering til I met Hick because it was always uncomfortable, guys trying to use their finger(s) like a cock.
When I was younger I could never really explain what I would have rathered (fingering oneself is very different from having someone else do it) so I either shut up and put up with it til I could distract him to something else or I directly said stop (if it was actually hurting and/or turning me off).
After I was with a woman the first time I realised fingering could be at least OK. She just put 2 fingers in my pussy and pressed up while circling her thumb on my clit. That was OK - didn't rock my world but it was better. But when I tried to exlpain that to a guy he just didn't listen and did the stabbing at me with 2 fingers thing. As did the next one. So I gave up on it again.
Hick, on the other hand (no pun intended), is all about g-spot stroking, gentle pressure and gauging my reactions. I could lie there cumming all day.
Going back to rob's point though, maybe my experience of oral is different because I happen to like the kind of clit stim most guys concentrate on when giving head.
