why do we close eyes, when you kiss a girl?

I think that when two people kiss,they concentrate on feeling the kiss.the world stops for them.the only things they feel are the brushing of their lips and the love they have for each other.also,an ex of mine said he feels the intensity of the kiss when he closes his eyes.

Hm this is an interesting question, to be honest I don`t realy know, but I remember that when I kissed for the first tine a girl I close my eyes and I didn`t know way. I think that when you are in love with a girl and she`s your girfrend when you kiss her you close eyes because you realy love her.

Let me see, based on experience....This is the one where time stops, the world disappears, your thinking vanishes, and you become the kiss. You lose your thoughts, judgment and all reason; you form one body and live only for the other. This kiss is not for the faint hearted and definitely not for those just along for the ride. Anyone who has ever been kissed knows that the sensations involved aren't confined to the mouth. Your facial nerve carries impulses between your brain and the muscles and skin in your face and tongue. While you kiss, it carries messages from your lips, tongue and face to your brain to tell it what's going on.
