Dulce de Leche shares a letter someone wrote to her pastor about her experiences with spanking and why she does not believe it should be preached from the pulpit. She shares her testimony of what it was like to be spanked and how it effected her. She also looks at the blurred distinction between spanking and abuse. This letter may be triggering so it is not for the faint of heart.
On a similar note is this post on The Journey about The Sexual Effects of Spanking.
