The Full Form of DFK is‍ Deep French Kissing.

In English informal speech, a French kiss, also known as a deep kiss or a tongue kiss, is an amorous kiss in which the participants’ tongues extend to touch each other’s lips or tongue. A “kiss with the tongue” stimulates the partner’s lips, tongue and mouth, which are sensitive to the touch and induce physiological sexual arousal. The oral zone is one of the principal erogenous zones of the body. The implication is of a slow, passionate kiss which is considered intimate, romantic, erotic or sexual. The sensation when two tongues touch, also known as “tongue touching”, has been proven to stimulate endorphin release and reduce acute stress levels. French kissing is often described as ‘1st base’, and is used by many as an indicator of what stage a relationship has reached.

You’ve seen it done in the movies and probably even in public — the French kiss, a timeless and passionate gesture of romantic affection where partners kiss while using their tongues. Whether you live in Paris, France or Paris, Texas, you can learn how to kiss like the French do without an embarrassing faux pas! If you want to know how to French kiss, see Step 1 to get started.

How to French Kiss

Keep your lips soft. A soft, smooth, and slightly moist mouth is ideal for kissing. Before you move in, you should make sure your lips aren’t chapped or dry so your partner isn’t distracted or put off by the state of your lips.^[1] If you want to soften your lips before you go in for the kiss, you should try these quick fixes:

• Use chapstick. Swipe some over your lips and press them together.^[2] (If you’re a girl and you have flavored chapstick, all the better!) The only caveat is that you should apply lip balm or gloss an hour or more before you kiss, so your kissing partner feels your soft lips, not the thick layer of gloss over them.
• Drink water. Dry lips are a sign of dehydration, so throw back a tall glass of water (or two).^[3] You should notice your lips starting to smooth out within 20 to 30 minutes.
• Lick your lips. If you’re really in a pinch and have no time to spare, quickly run your tongue over your lips and press them together. This should moisten them slightly without making them slobbery or slick.^[4] You can even lick your lips a bit subtly while making eye contact with your kissing partner.

Freshen your breath. You never want to have bad breath when you are about to kiss someone, whether the kiss is a French kiss or not. Because your mouth will be open in a French kiss, fresh breath is especially important. Practice good dental hygiene. If you know you are about to kiss someone, take a second to brush your teeth or at least rinse out your mouth with water.^[5]

• Always have breath mints or mint-flavored gum with you if you think there is a chance you might kiss someone while you are out. If you want to be subtle, you can quickly suck on a breath mint or chew gum for a minute in the bathroom, so you don’t make it too obvious that you’re ready to kiss.
• Avoid foods that leave an unpleasant aftertaste or residue, particularly garlic, coffee, onions, milk, and corn. If you’re on a dinner date before the big kiss, try to eat strategically.^[6]

Find the right moment. A good kiss—especially a first kiss or first French kiss—is the culmination of building tension and growing intimacy. Choose your moment right to make sure you and your partner are both in a mindset to really lose yourselves in the kiss. You should have privacy and should both be feeling romantic instead of stressed or distracted, for one thing. When is the moment right? It depends on your individual situation, but here are a few signs to keep in mind:

• You have complete privacy. Whether you’re alone on your balcony or sitting on a secluded bench in a park, you’re not worried that someone will interrupt you.
• The other person keeps dropping hints, like locking eyes and looking at your lips, or standing or sitting progressively closer to you. Regardless of your partner’s gender, their body language should give you a clue about whether now is the right time to make your move.^[7]
• You’re ending a date that went really well. In the car or on the porch are both good semi-private locations for a goodnight kiss.
• It just seems right. If you feel overwhelmingly compelled to kiss someone, don’t be too afraid to just go for it. (Just be prepared for an awkward or even troubling situation if you discover your intended didn’t feel the same way.)
• Ask. If you aren’t sure whether the other person is feeling it, bring up the topic. Better to get permission semi-awkwardly and go ahead with confidence than risk missing out on your chance to kiss that special someone (accidentally kiss someone who isn’t interested).

Make eye contact. Gaze deeply into the other person’s eyes. If you want to make your intentions extra clear, slowly move your gaze to their lips, then back up to the eyes. You can even make intense eye contact, break it for a few seconds, and then look back at the person.^[8] This is a way of showing the person you want to kiss that you’re pleasantly overwhelmed at the sight of them.

• Girls can even look at a guy, look down, and then look up through their lashes to be extra flirtatious.

Smile. If you’re really excited about the prospect of kissing the other person, show it! A smile keeps the situation light and fun, while helping them feel safe and relaxed. Make sure your smile is soft and genuine, however, and not a forced, too-wide, or overly intense smile. Just slowly and languidly ease your lips into a smile. Show your future kissing partner how happy you are to be in their company. Continue to make eye contact as you do this, or break it for a few seconds before you return it.

• You can opt for a close-lipped smile instead of smiling while showing your teeth, which might come off more as friendly than alluring or romantic.

Break the touch barrier. Once you’re alone with the person you like and you’re smiling and making eye contact, you can decide if you want to go in for the kiss without touching, or if you want to break the touch barrier first. This can mean sitting with your legs touching, holding hands, putting your hand on the person’s knee, stroking the person’s arm, or just giving a sign of affection. If you’ve kissed the person on the lips before, then breaking the touch barrier may feel more natural for you, and you should make an effort to touch the person before you touch lips so both of you feel more at ease.

• You can also break the touch barrier as you’re moving in to kiss the person. If you’re standing, you can touch the person’s arms, neck, or shoulders as you move in for the kiss. If you’re sitting, you can put a hand on the person’s back.

Move in. When the moment seems right, go in for the approach. In general, you should be moving slowly enough that the other person has time to say no, but not so slow that the moment loses its spark.^[9] When you start to get the feeling that your kissing partner is ready for the next step, you shouldn’t dilly-dally. Move your body toward their body until your heads are just a few inches apart. That’s when you’ll have to start angling your head for the best kissing position.

• Take it slow. The slow approach builds tension and anticipation. Move in at a pace that gives the other person a chance to consent (or not).^[10] When they see you coming in, they may move to meet you, so going slow will prevent you from accidentally bumping heads.
