This is an interesting question. I was close friends with an Inman , and we often talked about corporal punishment of wives since both our wives were spanked when they misbehavied. He never mentioned anything about him spanking another wife but he told me the topic came up in marraige counseling. He would listen carefully to the couple relate their issues and if felt the husband was at fault he would work with him to correct what he was doing wrong. But if found the wife at fault he would tell the couple that the wife should be taken home and given a good spanking. Often the husband didn't know how to do this and that became part of the counseling. But he never spanked any of the wives himself, that was her husband's job.
He was very curious how as a Christian I spanked my wife. Turns out the method we used wasn't that different. I used a strap , he used a very short whip, a nasty looking thing. He had his wife go the bedroom remove all her clothes and bed over the bed. I sent my wife to the study, had her remove all her clothes and bend over a reading chair.
