DDlg as it is commonly portrayed on Tumblr? No. More power to those for whom it works, but I am not among their number. My days of cuddly daddydomming are receding into the haze of memory, and I’m now more comfortable being a capricious and deviant paternal overlord/high priest. (One’s true calling oft goes unheard for far too long.)
Ageplay, on the other hand? It’s automatically ageplay if she’s young enough to be my daughter.
