I have no argument with terms defining roles, apart from the fact that I think we need to remember that we're also about having fun.
I'd hate to put new people off by too much rigidity, I think relationships can change at time goes on, what's important is that both care about each other.
There's got to be a balance between being serious & having fun- that's my mission, to work that out for myself. I couldn't care less what my girls call me, I find that if I'm deserving of a title they'll happily use it.
