Kiss to your life partner and family , is one of the most important expressions of love. Maybe it could be something learned or something instinctual, but the important thing here is that kiss helps you to have a big connection with those people who we love. The lips has lots of connections that send a signal to your brain,and that signal can make you feel good. Thats the reason why when you are kissing someone you can develope lots of feelings towards to the other person.
