I feel pretty similarly to you roxy, I really don't care too much, as long as whatever sex is happening makes sense in the story with the way the characters are being written, its all good. And yeah, more switching please (that would be a kink of mine if I'm honest.)
So, labeling, okay sure, why not? In fact, I think I'll go back and re-label it all just to see what I happen to write more often. I honestly have no freaking idea....and now I'm kinda curious.
