I definitely would shrink a woman in a world where everything about it was already figured out and safe and common with a partner who felt like her shrunken self was her “true” self. It just feels like it makes sense to me.
I’d want to be in control of her shrinking, though. Sometimes I’m in the mood to cuddle a proportional three foot tall woman, sometimes, I want to feel use a four inch woman as my little lap fidget toy.
