#11[ Could be a woman, or even a teen aged girl who has learned she enjoys spanking, or receives sexual gratification from being spanked.
Ahhhh well, this could fit into either #7 or #8, couldn't it?
For #7, she has erotic reactions to the idea of being spanked, yet isn't certain about her feelings until she experiences it.
For #8, she's aware of her spanko-bottom tendencies, thus she intentionally provokes other people into spanking her, however in a playful, teasing manner. (This 'misconduct' is/was called "bratting" by submissive participants in spanking-oriented relationships.)
This female (#11) arguably might be a separate 'bottomish' type if she gets spanked by simply asking someone else to spank her, or if she deliberately provokes a spanking, but does so by seriously challenging an authority figure and/or intentionally being caught breaking institutional rules.
The motivation would be the same as in #7 and/or #8, yet the methodology (how she gets herself spanked) could be different. Is that enough to make it into a separate category? I'm uncertain about that...
