I only spank women and I do have a dress code. Dress code is single layer skirt or dress with all cotton panties. Before any implements I spank through all layers of clothing to get the bottom properly warmed up. The panties are the most important part, all cotton panties traps the heat inside without burning the bottom. The proper "warm up" helps to minimize and depending on the spankee avoid welts bruising blisters. However the warm up session is not a patty cake session, my hands still strike full force.
