Oral for her: ladies what feels better and usually makes you cum?

So basically I love the feeling when someone goes down on me but I havent had the big O yet. I have smaller clit orgasms but nothing like the extreme ones you would see in porn or TV. I'm wondering if I'm not so sensitive because I definitely need a lot of pressure and I take a long time to get there. I feel bad for my dude because hed be down there for like a half hour and I'm just getting warmed up. Thing is is that when he uses his fingers I get there much quicker. I love the feeling of his tongue and it's so hot that he loves to eat me out but it just feels better with fingers. Anybody else like this?
