You ever think about this fetish in like, the context of your masculinity? As a man you're supposed to provide for women, protect them, be their rock and emotional support, and put your life on the line to keep them safe. But when you're a tiny, you can't really do any of those things.
Part of that is actually very liberating, finally getting to be the vulnerable one, showing your emotions, letting someone else protect and care for you because you're the prize to them. But I'd be lying if I didn't say 2D > 3D for this purpose cause IRL women would still get the ick from you not being manly enough around them while also not absolving you of any of the sins of toxic masculinity even at an inch tall. Probably why this fetish is dominated so strongly by men too.
