How and where do you touch a guy when you kiss?

Not everyone has the same sensitive spots but you could try light touches to the back of the head, the ear, the side of the neck, the cheek. Run your finger nails down the center of his chest. One of my favorites, which you can do right in front of other people and they won't even know what is going on, is a light stroke down the back of the upper arm with your fingernails, on the tricep muscle - only you and the person being touched will realize that it felt good in a sensual way...give him a smile when you do it so he knows you meant it.
