>>34700376For me there's something exciting and sensual about someone being put into a new form and exploring how their new body works. I don't know why the unwilling bit is a bit more appealing, but it might just be the drama of having conflicted feelings combined with the unfamiliarity of a new body. That being said, I'm really only into genderswap and monstergirl transformation which is a frustratingly small portion of the transformation fetish.
