Mainstream Spankos

Bogey and Becall at Our Bottoms Burn linked to a surprisingly well done article at Fox on Sex about spanking.

I remember some sort of survey a while bak that I quoted in a previous post about how worldwide 20% of consenting adults are spankos. However, in the US for some reason that number rises to something like 40%.

Can't help but wonder what makes the US so spanko-able.
