If you mean cock teasing by touching than i think the best way to do it is to play with it awile either by rubbing it with your hand or kissing all over it. What gets me going the most is when my balls are caressed while my wife kisses all around the shaft and the head untill im ready to go. Then all at once she stops and gives me a chance to recover and all at once she forces it inside her wet pussy. After that it doesnt take long before i explode. Sometimes cock teasing leads to the best kind of sex.
