I, too, am a serial mongamist. I generally find that if one relationship has me on Top, I end up on the bottom for the next. I was lucky to have one where she and I would switch based on mood and how our day at work went.

Sometimes, it is hard to switch within the scene but some of the hottest scenes I've ever been in have been when the sub turns the tables on the domme and makes her take the role reversal and love it. Topping from below can be pretty hot!
