Likely one of the Kong movies was an influence. Or something along those lines. But my first real memory of being interested in this fetish came before I even knew about being sexually aroused.
I was playing in my room, pretending to be some giant creature or the like battling an army of my action figures. As was a staple of kids programing at the time I, as the giant thing, didn’t crush or trample the female figures. I captured them in my hand.
Still wanting to play with the other figures as I “rampaged” I needed a spot to place the female formed plastic figures. And my young brain thought, in my pajama bottoms. But the fell down the leg. So, in my briefs they went.
As I played the tiny lady shaped toys rubbed along my penis. Then suddenly my penis did something I never seen it do before, it got hard. Pressed against my briefs and pajama bottoms with several lady action figures pressed between them.
Now, I know what had happened. But at that time my young mind assumed since I was pretending to be a giant scary monster that I was somehow, in a strange way, scaring myself. And that had made my penis stiff in fear.
That is my earliest and slightly embarrassing first memory of having an interest in this fetish.
And that would be distracting.
