First, let me state that this is just a beginner’s guide of things I’ve found helpful over the years. However, nothing beats experimentation and communication with your partner to figure out exactly what she likes.

Have her lie on her back and start with her face. Kiss her lips, her neck, her shoulder blades, move down to her chest and don’t be afraid to give her nipples some attention because they get ignored sometimes. Work your way down to her belly, then her hips, her thighs, her calves. The idea here is to give her lots of attention, let her know that you love her body and to make her anticipate what you’re going to do to her. Now move back up and find a comfortable position on your belly between her legs or move her to the edge of the bed or couch or whatever and get on your knees. Sometimes it helps to wedge a small pillow under the small of her back to give you easier access to the area, but that’s totally optional, don’t let it interrupt the flow of things.

Now is the time to tease her even further, kiss and nibble on her thighs, brush your lips over her labia, kiss around it, hover over her lips with yours and let her feel your breath. Make her ache for it, she will want your tongue more than anything. Now give it to her.

Start by giving her a few big licks with a firm flat tongue, from bottom to top, just brushing her clitoris before you start at bottom again. This lets you taste her and how much she wants you which should make you hungrier than ever.

Once she is squirming, focus your attention on her clitoris. If your’e completely new to this, the clitoris is a small bud of extremely sensitive tissue that is protected by a hood at the top of her labia. It will usually stiffen up a bit when she’s aroused and will be roughly the size of an eraser on a pencil. Some are larger some are smaller.

Now that you've located it, focus most of your attention here. Don’t be too aggressive with it if it’s your first time with her as some are more sensitive and hurt when stimulated too much. Start slow, imagine you’re making out with her pussy and the clitoris is the tongue. As with kissing her mouth, suck on her, flick your tongue against her, sometimes softer, sometimes with more intensity, but whatever you do. NEVER EVER BITE. Now, Swirl your tongue over her clitoris, try variations of back and forth, up and down, or whatever you can come up with to see what she reacts to most. She’ll let you know. Once she does, concentrate mostly on doing what she likes, but swap it up every now and then so she doesn't get numb to the sensation. Also, you can gently pull back on the skin right above her clitoris (not her labia, her actual skin) to expose more of her clitoris and a bit of her clitoral shaft. You’ll be able to feel it with the tip of your tongue and it’s extremely sensitive as well. Don’t be afraid to give it some attention.

I should also mention that some people like to insert a finger or two inside of her for some internal stimulation. I almost never do this though as I believe it takes away from what I’m doing with my tongue. Going down on a woman is all about clitoral stimulation and penetration (as I understand it) takes away from that. If you’re good at it, you shouldn't need your fingers, but if she asks for them certainly give her what she wants. When the time for fingering does come, read over this and give it a try.

When she’s getting closer to orgasm, she will likely start to writhe and involuntarily try to wiggle away from you, don’t let her and definitely don’t stop. Lock your arms around her legs and hold her steady. At this point I like to gently suck her clitoris between my lips and increase the intensity of my licks or push against it and “grind” the flat part of the tip of my tongue against it. If she doesn't come after doing this for a few minutes don’t push it, back off a bit and try the gentler approach for a while again.

When she does begin to climax, you’ll definitely know it. Hold on and don’t let her wiggle away. Don’t stop until she’s begging you to. She’ll be extremely sensitive, but I still like to tease her a bit, soft kisses on her swollen clitoris to make her shudder, kisses on her thighs, licking up the wetness you've generated, gently blowing on (not in) her to cool her off. Give her a few moments to recover then ask if she wants more. Oblige her if she says yes.

Good luck, making a woman come with your tongue will make you feel like a god.
