First things first, kissing is the absolute best thing that ever happened to our lives!

Unless it's not. For example, when your kissing partner tries to drown you in his saliva, maybe it's time for a talk? But, you know, it's mainly the best.

Over at, they consulted with kissing expert Sheril Kirshenbaum, author of the book The Science of Kissing: What Our Lips Are Telling Us, to explore what different types of kisses mean in relationships. ​"Kissing is so important to long-term bonds. It helps maintain a relationship,"​ she says.

Here's some kisses, finally explained.

1. The Single-Lip Kiss

The Single-Lip Kiss is a kiss that is truly all about love. Rather than diving into a more aggressive kiss, each person focuses on kissing only one of their partner’s lips at a time.

Bernard Metlzer said, “Happiness is like a kiss. You must share it to enjoy it.” This kiss is absolutely a shared experience. There is a give and take involved that indicates a deeper love for one another.

Whether new or old love, this is a bond that you will want to continue to explore.

2. The Cheek Kiss

The Cheek Kiss is a kiss that is all about conveying that you like someone. Rather than dive right in at the mouth, one person lays a gentle kiss right on the other’s cheek.

This kiss is about friendship and affection. The person planting the kiss may have romantic feelings for the receiver, but this moment isn’t about that romance. This is about a true fondness, conveying the message that “I like you.”

A kiss on the cheek that comes years into a relationship may just indicate that the all-important friendship still exists underneath it all.

3. The Closed Mouth Kiss

The Closed Mouth Kiss is one that shows you are not quite 100% comfortable with one another yet. Each person keeps their lips firmly closed, not allowing for moisture or tongues to touch.

This kiss indicates that perhaps this is a new relationship where you haven’t let your guard down yet. Charles Dickens said, “Never close your lips to those whom you have already opened your heart.”

This kiss in a longer relationship could be a sign that you are each putting up emotional walls and that communication may need to be improved.

4. The French Kiss

The French Kiss is a kiss that is all about wanting to get to know the other person even more. Each person uses their tongue to explore the inner workings of the other’s mouth.

This kiss is all about exploration – both literally and figuratively. Ingrid Bergmanfamously said, “A kiss is a lovely trick designed by nature to stop speech when words become superfluous.”

When you’ve run out of words, or when words just don’t seem to be enough, the French Kiss is exactly how to let your partner know that you want to be closer and that you wish to know them on a deeper level.

5. The Spiderman Kiss

The Spiderman Kiss is one that is all about spontaneity. Based on the famous movie scene, this upside-down kiss is probably best performed by us non-superheroes when one person is sitting or laying down.

This kiss shows that your relationship still surprises you. You each still share a sense of excitement, and you love the opportunity to sneak up and lay an unexpected kiss on your partner.

Whether new or old love, you each care enough to keep finding new ways to express your feelings.

6. The Nibble Kiss

The Nibble Kiss is all about being feisty. One person gives the other one a little love bite on the lip, hopefully not so hard that it draws blood or pain.

This kiss shows an underlaying passion that is often best expressed physically. You likely have a healthy, and perhaps athletic, sex life. You don’t mind being a little rough with each other, as this only spices things up even more.
