With a friend - 2 guys working on her at the same time, she will go nuts..

With a cold!.....

That answer depends on the woman in question. Everyone is different, and respond to different techniques. But I have found that most women do have certain preferences in common. - She probably knows better than you do what gets her off. It really doesn't hurt to ask things like "Does this feel good?", "Faster?", "Slower?", etc. It will make the learning curve more tolerable and show her that you really care about pleasing her. - A good rule of thumb is the wetter, the better. Don't slurp and slobber, but things like flavored lube can be a lifesaver. - Don't just focus on the clit. Pay attention to everything from the inner thighs inward. - Don't attack the clit, either. Don't use a lot of pressure on the clit right away, go slow and gentle, licking and sucking on her lips, (inner and outer), running your tounge inbetween the lips, gently flicking the clit hood, tounge fucking her, etc. What would be considered too hard at first might feel terrific when she's good and worked up, however. - Don't just use your tounge, use your whole face. You're not so much licking and flicking as you are licking, flicking, sucking, rubbing, and blowing. (Blowing air gently on the clit, I mean. DON'T try to blow air into her like a balloon. It can cause an embolism.) - This one may or may not apply to most girls, but I've never been with a girl who wanted my face anywhere near her pussy unless I'm clean shaven. Some girls may not care, but a lot of them don't like to feel like they're getting head from a belt sander. - Remember to at least act like you're enjoying it. You wouldn't like it if she looked like she would rather be balancing her checkbook while she's down on you, right? She's the same way. - Once she starts doing things like bucking her hips, pushing her crotch into your face, squeezing your head with her thighs, etc., that means you're getting there. Don't stop, slow down, speed up, go harder, go softer, or do anything else different. What you're doing at that exact moment is working, and if you change it up, you might ruin it for her. - Be prepared for the long haul. Depending on the girl, the time of day/week/month, what kind of day she's had, the alignment of the planets, etc., it could take a few minutes, or it could take forever. So it would behoove you to figure out beforehand a position that both of you can tolerate for at least 20 minutes. These are just a few pointers that have worked out for me. As far as specific techniques go, I've had good luck with spelling the alphabet on her clit, and sucking her clit into my mouth after she's good and warmed up and kinda rolling it around with my tounge.
