Summary:

• Kissing is a way for us to communicate through pheromones, the parallel of dogs sniffing each other’s butt.
• Most women will not have sex without kissing first while men would.
• Kissing reduces stress for both men and women.
• Kissing generates chemicals that promotes bounding and long term attachment for men, but not so much for women — who need lot more.
• Most of us tilt our head to the right when we kiss.

Happy kissing!
