Yes this is very true, I agree. But it should be a little responsibility of the female, too. They need to voice it and be like "Ah yeah, it feels great right THERE! Don't stop" ya know what I'm sayin'? haha. Or else the guy will just switch up his pace and you won't be satisfied fully.
Like for example, the first time I fingered my girlfriend, I really didn't know what I was doing honestly. When we talked afterwards, she said that she nearly orgasmed 3 times or something, but everytime she was about to, I would move my finger placement to a different spot and it would be lost. So now I gague her reactions to certains spots and then that's where I maintain my strokes.
I think that it all sounds so very complicated with cunninlingus, though. What with motion, pressure, speed, etc... oh my. This is going to be so difficult.
