Being labeled a "Bottom" because I like to be spanked by women. I prefer Spankee or you could just call me the guy who likes to be spanked by women. Thank you
Well, AFAIK objectively that's just basic spankophile terminology--I don't perceive it as demeaning, at least from fellow spankophiles.
However, equating "bottom" with "submissive" strikes me as potentially inaccurate--lots of people like to be on the receiving end of butt-blisterings without having an overall D/s relationship with their chastiser(s), although they'll likely behave submissively during a spanking session.
I find it interesting that "top" has only one spanking-oriented meaning, while "switch" and "bottom" of course have two: "The switch snapped her switch across the bottom's bare bottom..."
