I once had a Domme (a switch) who was also submitting to a male Dom at the same time. Sometimes I too noticed a difference in dynamics that may be like what you posted about. But at least to me, it really had less to do with the fact that she was both domming me and submitting herself and more to do with what just seemed the way she sometimes felt more dominant than submissive or more submissive than dominant. When she felt strongly dominant that was very apparent in the way she tasked and trained me. When she was feeling more submissive, our relationship became more akin to vanilla than BDSM related if that makes sense. To me it was just part of being in a D/s relationship with a switch. I didn't respect her less or find her less able to meet my needs as a submissive knowing that she was also submitting.

I prefer the sub role and have no plans to change yet I actually think I could be a switch in a circumstance where I had a relationship with a female sub who was more submissive than I. While I know it isn't quite the same, most men are simply raised in our culture to be dominant in everyday life and so I think that could transfer to a D/s relationship. In fact, in my vanilla sexual experiences I have always been the initiator and the top and it feels quite normal. But from what some of the female subs here at the Library have said, they would have a hard time submitting to a male who also submitted. So it may be a sex-dependent construct. I can only speculate but I'd personally think your situation with a relationship involving a female switch, would be less problematic.
