I've noticed there are some stories involving children being spanked for example. I don't really get why that would be entertaining, maybe someone could explain that to me?
Well, I would venture that the great majority of spankophiles who enjoy child-spanking stories envision themselves in the roles of the punished children rather than the (usually adult) disciplinarians.
I remember discussing this subject some years ago on the SSS newsgroup, because a 'newbie' poster there was upset that so many people had "fantasies about beating kids," as she interpreted the situation, based on the number of posted accounts of children being soundly chastised.
BTW, I'd venture that "discipline spankings" which you (as the recipient of them) find erotically stimulating at the conscious level, aren't truly all that punitive in nature...
