It's a discussion of pros and cons. I was just offering up my view. My feeling is that sometimes it's easier to use lables for things to have a common language to fall back on. Of course there has to be more discussion on what the relationship expectations are for everyone involved but if you are clearly looking for someone to have the occasional date with due to time constraints ect. why not be upfront when meeting people saying that you are looking for a secondary? Seems to me that it's a good way to avoid crushing people's expectations if they are looking for more from you than you are able to provide.
