I prefer the dom role but will switch. There is a little game I like to play where we pretend you are a stripper giving me a private dance. Like a very stict club I'm not allowed to touch you with my hands. You however can do anything you want to me until...You kiss me on the lips. That kiss signifies the switch, where I can use my hands and I become the dominant one.
So, you get decide how long you stay dominant and I think the kiss, which you have deprived me off till this point, is a wonderfully sensual and symbolic way of signifying it's time to switch. I've only had a few women do it with me but my God, its a damn hot time.
