My core kink is a desire to be emasculated, controlled, and humiliated. So for me it’s a 3-way combo:
Diapers imply that not only am I not a real man, I’m even not even a boy- I’m just a helpless infant with no control.
A stout butt-plug is an invasion and a submission, a reminder that my most intimate parts belong to my master/daddy/dom.
Finally, a chastity cage buried under that thick diaper holding that plug in tight. My pathetic dingle is locked and buried, and may as well not exist.
This treatment leaves me properly focused on the dangles of my sir, and other real men–and desperate for prostate relief, the only way I can get it.
