For as far back as I could remember, my father "spanked" (more like beat or whipped) me totally naked. He always made me strip down to absolutely nothing and give me dozens of hits with a leather belt. It didn't matter if I was on my period or not. I can't tell you how many times I had bloody welts on me from my calves up to the middle of my back.
From all that I've read - and I've read about this crap for years....your father was using his power to humiliate you - but, most likely, just as strong or more - he was making a sexual situation "happen" for him. Through the beatings with the belt (my father used them too), stripping you down naked, you're laying down for him, his complete authority over you, even your humiliation as a young sexual woman, all were designed to make him more sexual & powerful.
It's also of interest that your welts could be hidden by normal clothing by you. Another trick that beaters use - and victims fall prey to - hide the evidence. Seems that men/women/parents who use weapons know precisely where to hit so that the welts & bruises can be covered. Perhaps their parents taught them?
That was beastly of him - and you have a complete right to your righteous anger. I'm glad you expressed it to him, even though it cost you dearly. At least you have the memory of standing up to the bastard. Congratulations.
Your father had no right to treat you that way, no matter what his beliefs. It was wrong of him. To be in a religion that quasi-encouraged him to "discipline in righteousness" however he felt appropriate just happened to be your bad luck in time. Born to the wrong man. But you survived marvelously.
