I'm pretty open. Considering the broad spectrum of kinks, I can't necessarily accommodate all the needs of a partner, and they can't always accommodate mine. I would feel selfish if, for example, I started playing with a switch long term and I'd be like A: I can't dom you and B: you can't get dommed by anyone else because we're devoted to each other now. I think it's only fair that if I can't meet all the needs of my partner, I at least give them the freedom to meet those needs in other ways. Likewise I wouldn't want to be in a position where I have to deny a part of who I am, because that's what my kinks are.
