As humans, we seem to be very interested in putting our lips on the lips of others as a way to show affection. Has anyone ever questioned that? Brit.Co has done some of the research to figure out why that is what we are told is what we do to be affectionate.

The biggest speculation is that it was an evolutionary tool for humans to find a suitable mate because it used so many of our senses. Taste and touch are involved by default, but you are also close enough that you can smell them as well. It helps you paint a good sensory picture of the other person.

Kissing also helps us determine the other person's personality! Haven't you ever been turned off by someone who was just too aggressive (or too shy) when it came to how they kissed? Studies have shown that the amount that a couple kisses is directly proportional to how satisfied in their relationship they are.

Kissing can be fun! Whether you've found your mate or not, sometimes you have to kiss a lot of toads before you find your prince charming.
