What percent of grown daughters are spanked?
Statistics on spanking of adult daughters are not available. It is known that spanking is a practice more commonly used for small children so it can be assumed that adult daughters are rarely spanked.
My wife has always liked to be spanked, long before I met her and since she hit puberty. It has to start gently and then get harder, and then she take a surprising amount of punishment. She doesn't feel it as pain though, she says, she enjoys it. I suppose I haven't really explained it. Some people enjoy jumping into very cold water because the trauma makes their brains release pleasure hormones. Go figure.
