It's not the abuse which made them that way, but
how they responded to the abuse.
Namely, they began masturbating to the stressful memories of being bullied, belittled, and cucked, which created and reinforced their sexual fetish(es)
Ejaculation, of course, serves a stress-relieving purpose by releasing endogenous opioids, which creates a temporary emotional stability. Perversely, opioids are precisely what facilitate feelings of social attachment (love), and so these people get to the point where the only way they can feel interpersonal connection anymore is by replicating their intense, traumatic experiences.
The exact same thing is true for roasties who were raped, and developed a rape fetish.
And it also explains cases of young boys who get raped by an older man, and proceed to become a submissive homosexual.
