I think part of it has to do with specific orientations during bdsm or D/s, because I can only ever be submissive to a man, because thats what feels natural to me, like the world is right when Im serving, but in regular everyday life, I sure do find the sight of a pretty girl quite yummy, just not to engage in the lifestyle with...so female sub to men, bi curious, something like that, geez labels are weird.
