Outside of Ageplay, I'm a Switch on most things, and mostly Impact Play. Even tho the interests overlap, it's a different thing. I am not a Switch with Ageplay tho.
My Ageplay sweet spot is like 4 years old. Too old for diapers, embarrassed when I have to wear them, but not quite keep dry yet. One of my fave scenes I had was a Mommy that had me wet my big boy underwear and pants. The scolded me about my wet pants, then pulled my pants and underwear down and off, then lighting up my butt with a leather belt. Then wipes, powder, and diaper. After this Mommy hugged me, held me, and told me she loved me. It hit THAT nerve and I cried. It was really amazing.
I have everything from floggers to crops to paddles of different variations. I have been spanked when I was trying to hold off on wetting that diaper, and somewhere between "this isn't quite fun anymore" and safewording out or Mommy stopping, losing control and wetting my diaper, then being scolded for it was incredible too.
