I did get spanked as a boy but probably not as hard as many of my contemporaries.
My mom usually just gave me five or six spanks over my underwear. I would cry, of course, and it sucked but the punishment was actually pretty mild and really not too bad.
If my dad spanked me, I got more spanks and it would hurt more but my butt would stop being pink pretty fast and I was never left bruised or anything. To be honest, just hearing my dad yell ‘Dennis! Get your ass here and get those jeans down!’ was enough to pull me up straight but I would always obey and take my punishment.
Getting the paddle at school was worse, even though it was given over jeans. All the teachers used it and they would spank children in front of the entire class, which was really embarrassing, especially for girls.
I got paddled around about once a month and my butt would be sore and bruised for a couple of days afterwards from the two to six swats of wood put across it.
