As has been mentioned numerous times, all girls are different and enjoy different things. Fortunately, there are a surprising amount of ways to use your tongue and lips for this activity and finding those things is a mutually enjoyable adventure. There is a lot more to it than lapping away at the clitoris for 30 minutes. In fact, attempting that will most likely earn you a good smack upside the head as after a while the repetition is more uncomfortable for the girl than good.
Rather than go in (no pun intended) with a plan of execution, erase your mind of pre-meditated techniques and just explore. You’ll learn right quick what she liikes and doesn’t like. Just because you find something she likes doesn’t mean that’s all you should do.
My generalized rules that should apply to the art of cunnilingus with any girl:
Foreplay is a must. Touch and tease and kiss everywhere. It’s not just for the man’s benefit!
Don’t consider it a chore. Enjoy doing it and enjoy bringing the lucky girl pleasure, it’ll show. Girls know.
Don’t be afraid to get messy. As things progress you’ll want to really get in there and it can get messy.
Start slowly and gently. Nothing will earn you two legs squeezing all the blood from your head faster than diving full bore for the clitoris from the start.
Remember that there is more to her than a clitoris. Every part of her becomes even more sensitized as she becomes more and more aroused and the vagina itself has many areas to explore. Remember your high school health class lessons about where most of the nerves are and you’re halfway there.
Do not use your teeth. Ever.
Sometimes a little suction goes a long way. Note: a little. It can also be a nice way to mix things up and give your tongue and jaw a short reprieve.
Try not to focus on one spot for too long. As a demonstration, rub your finger over your nipple for 20 minutes and see how good it feels. Of course, at some point you’ll want to focus on the clitoris enough to bring her to orgasm, the key is knowing when and that’s dependant on the girl. It helps to alter your technique slightly once in a while. You can alternate up and down flicks with the tip of your tongue with side to side with the flat of your tongue (being sure to use your head a la Stevie Wonder to maximize differing angles of pressure) with writing letters of the alphabet with anything else you can come up with. Variety is the key.
Changing techniques brings several advantages. It keeps her from the aforementioned friction “burn” (for lack of a better word), it allows you to rest certain muscles (you’ll tire quickly, especially at first), and if done correctly you can keep her at the tortuous level of pre-orgasm for an extended time, which while perhaps a little frustrating to her at first really pays off when she does reach orgasm. Smaller men have been known to be thrown across the room…
Stay with her no matter what. When she approaches orgasm she may start to buck her hips and if you lose contact you risk making her lose her focus and essentially having to start over again. That doesn’t mean latch on like a leech, just expect it and be ready for it.
Use your fingers. Giraffe described ideally how it should work, but finding the G-spot isn’t always as easy as that. Don’t be disappointed if you can’t locate it and don’t spend an inordinate amount of time and focus trying to. If you find it, you’ll know immediately. If not, gently explore and you may get lucky. Either way some gentle insertion won’t hurt your case.
When she tells you to stop or when her hands come down atop your head to push you away, stop. Trust me. You may figure you’ll just go for two, but she’ll crush your head. She knows when where and what she wants and it’s her decision.
As advised before, you may want to wipe your mouth before kissing her (and some girls may not want to kiss you at all until you’ve brushed your teeth) but you will also want to be very careful about touching her anywhere at this point. She’ll likely be so electrically charged at this point that even the slightest touch could send her into fits.
Lastly, though it’s been said it bears repeating. Enjoy yourself and she’ll enjoy it all the more. Your reward should be bringing her pleasure, but don’t be surprised if she decides to reward you even further.
