I think that one of the earliest instances in my childhood which forshadowed a good chunk of my preferences (that I know of) was when I was a toddler and watching season 2 of Winx Club, specifically the last episodes
The mc is kidnapped by one of her teachers at fairy school, who was actually one of the villains in disguise (recalling memories from a more mature perspective, the teacher was grooming her, I'm pretty sure), and who she had trance sessions with for plot related reasons
Those sessions were both helping her and secretly planting, I'll call them pillars, in her mind
The mc was taken, bound to a metal or stone table or altar, and a ritual was forced upon her, making her a loyal slave to the main villain (who was not the teacher if I recall correctly)
My explanation is lacklustre, but for now putting in writing from what I already acknowledged to be true is the easiest way for me to express my feelings
The conclusion, -which has a non-zero chance to be copy-pasted in the pinned post- is that I like, at least on an imaginary level:
*I have problems of expressing this: fear of not doing it correctly (and I'm not sure if I'm doing it correctly right now) and unintentionally being an ass to actual victims by expressing it
**unrelated to everything above, but it came up as the first suggested word and I'm impulsive
