Sesame oil has a relatively low smoke point, so it should not be used for frying; I use peanut oil as my basic cooking oil for Asian recipes. I use sesame oil in marinades and salad dressings, and as a finishing oil for stir fries. It also goes rancid relatively quickly, so I keep mine in the refrigerator to prolong its shelf life.
Anyplace where people argue about food is a good place.
