The trouble with 'other' is that is reinforces some stereotypes about switches - the 'misc other', do what you want, change mind in the middle of a scene view which is generally inaccurate. Of course, it is difficult to work out a better label.

Top and bottom are good labels as well as they do tend to describe the need for kinky sex without the requirement for submission or dominance. In fact, in a relationship between two switches you may sometimes see one being Top for a scene and the other the bottom then the next time they play they change places. Thats what switch means, technically, you switch roles depending on circumstances (personal feelings, the person you are playing with, the rota you set etc)
