You will understand this better if you have ever been in a relation and have kissed your partner. Your style of kiss gradually changes as you move on in your relation. In fact, it has happened a lot many times with me that I have kissed my partner and then was able to analyse something about how was was her mood while kissing me.
So, the point which I am trying to portray here is that you can easily analyse the stage of a relationship you are in with your partner by the kind of love-locks that you had.
You both have been craving for each other for a long time, that's when you meet and have a gentle and passionate kiss!
This type of kissing tells that your relation is still to take-off. This way gives you a slight taste of your partner's water.
A full too tongue play is what this term means. Here, the kiss says that the couple are quite playful with each other and they love to experiment.
This type of kissing takes place when the couple can not get enough of each other. They just seem to have a lot of attraction towards each other.
This kiss suggests that the kissers are inexperienced and are both new to the world of kissing!
This type of kissing throws light towards the powerful intimacy and hunger for each other that is developed between them. In this, they lick the lips and all around them too.
This type of kiss says that the relationship is more of a friendly one. It may also suggest some care about each other.
