A French Kiss is an open mouth kiss, which involves moving your tongue in and out of your partner's mouth as they do the same. It is a kind of kiss, which requires practice and most people find it sloppy and unpleasant at first.

Although family members may sometimes kiss on the lips, a kiss using the tongue almost indicates a romantic or sexual relationship. French kissing stimulates the lips, tongue and mouth, which are all sensitive areas to touch. It is considered by many to be very pleasurable and highly intimate. Unlike other forms of "casual" kissing (such as brief kisses of greeting or friendship), episodes of French kissing will often be intense, prolonged, and passionate. It may be the beginning of a period of "making out" or "sexual intercourse". Because of the intimacy linked with it, in many regions of the world tongue kissing in public is not acceptable to most, particularly for an extended time.

The following are the tips to know how to french kiss

Freshen your breath: You never want to have bad breath when you are going 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 particularly important. Carry mints with you if you think there is a hint of a chance you might kiss. Avoid foods that leave an unpleasant aftertaste or residue, particularly garlic, milk, onions, and corn.

Moisten your lips: Dry lips do not move well together, but you do not either want them to be dripping wet. Simply a light brush of your tongue over your lips will be sufficient to moisten them. A little bit of lip balm can help, but be warned, lipstick can be awfully messy so blot before you kiss.

Angle your head: If your mouths meet together, your noses will get in the way, and you will not be able to kiss deeply or smoothly. To avoid this, slope your head slightly to one side. Make sure you do not both slope your heads to the same side.

Close your eyes: As you approach for the kiss, look into your partner's eyes and once you are close to theirs, close your eyes. It can be a bit of turnoff to be kissing and going cross-eyed.

Start with a gentle and soft closed-mouth kiss: The French kiss is an open-mouth kiss, but do not lunge in with your lips amazed like you are going to eat them; instead, open your lips very slowly. Even after you have added French kissing to your romantic repertoire, it is generally better to start a kiss with closed lips.

Explore with your tongue: If you and your partner seem to be enjoying the open-mouth kiss, gradually try to open your mouth a little bit more and gently push your tongue a little farther into their mouth. The tongue is very sensitive, and the simple act of touching your partner's tongue with your own will be very pleasant and stimulating for each of you. Do not stick your tongue too far into the mouth, as this can be a bit turn-off. Instead, gently and playfully touch tongues.

In a tongue kiss participants exchange saliva, which would frequently be considered disgusting in other contexts, but which may add to the passion and excitement of the sexual kiss. Although kissing does not transmit most STDs, the exchange of saliva in a French kiss may increase the chances of catching an orally transmitted disease.
