I’ve seen a few references on your site to being spanked on a wet bottom, and how it hurts a lot more somehow than a dry tush. I can confirm that experience, as my own mother saw to it that I had a wet behind every time she administered corporal punishment.
I think I probably got a few informal slaps and smacks when I was younger, but ‘proper’ spankings for me started when I was around six years old, I think. These always took the same form.
