Body seems less important than character/personality chemistry for many of the reviewed experiences but it obviously plays a factor in attraction.
When searching providers http://www.eccie.net/providers.php?do=search there are 7 "Build[s]" from which to filter results:
Athletic
Average
BBW
Curvy
Petite
Slender
Voluptuous
Currently, there are 110 Provider Showcases for KC Metro.
Here's today's breakdown:
Athletic 17
Average 13
BBW 4
Curvy 36
Petite 17
Slender 19
Voluptuous 3
Undefined 1
So begs the question, how do providers define their build?
