I love a ball gag. It is a very fetishy item. What I really love though is my wifes stockings stuffed into my mouth then held in either with tape or a scarf/cloth/the other stocking. As for my wife. I prefer her gagged with her own socks os stockings.
My alltime favourite gag is my wife's foot in her stocking or tights. My second fave gag is her barefoot.
