I understand the gross one, but why bimbofication?
Hard to explain, it's kind of part of those things that you can clearly feel disturbs you and you prefer not dig too deep why... But what I can tell you is that it ties up with body modifications, if tattoos are not a problem with me (I have some art tattoos myself), even piercings, the real modifications like monstrous esthetic chirurgie like you can see stars doing that make them less humans and more like aliens with a strange uncanny valley effect (I mean look at Nicole Kidman, and don't be triggered please, it's not about shaming someone, but about what the person make you feel), follow up implantations (meaning like balls or stone under the skin for example) and scarifications... All this are things that psychologically disturb me, I know they are part of a quest for people to better accept their body, but to me it's like seeing people trying to alienate themselves from their humanity (again, I know it's reductive and some people do this in a very nice fashion, but like I said before, it's an uncontrollable feeling it gives me, not a judgement on people's personal choices).
And had to that the erasure of one-self for the desire of another and it kind of make things really unhealthy. Though you could argue what about dom/sub play, bondage, slave play, etc... well, all this is temporary, you can have a fun session that get your boat floating and then slip back into whatever life your living usually; that's not the case with bimbofication, you literally change and transform your body to permanently become another person usually to become a pure object of desire for another person, figuratively erasing mind and body both... This simply disturb me (and again, I know it's caricatural or extremist vision and that we're talking about fiction here, but it's hard to write about something that mentally and physically disturb you).
AGAIN, before anyone take offence, it's not a judgement on anybody's kink, it's me trying to explain why something literally makes me feel disturbed or distressed when I witness it. It's one of those incontrollable things that has probably some deeper origins, but I prefer not to touch because it's easier not to.
