How is a Kiss so "Magical"?

How is a kiss so magical? How come pushing two soft lips together feel and seem so amazing? A kiss that leaves you thinking.. everything stops and you're speechless.

Many of the passionate kisses I've had made me feel weightless.. kinda like a super love-trance.

My first kiss left both of us speechless and we just fell (We were sitting on my bed talking to one of our friends) back on my bed and after about 8 seconds of just staring at each other smiling.. It was just incredible...

Sorry, I'm talking about my first kiss.. I tell i'm writing really badly.. Sorry.

But really.. How come kissing is such a strong sign of love and why is it so magical?

I disagree OP; Probably like yourself, I like kissing but truth be told, it doesn't mean anything to me except getting a semi lol.
