so, paraphilic disorders are known to be heritable...or rather the *tendency to develop a paraphilic disorder. Which one you end up with is sort of the luck of the draw. In short, yes it is partly genetic. As with most things its a combination of genes and environment. This one seems to correlate heavily with early childhood neglect/abuse/trauma, and also has a fairly high comorbidity with cluster B (borderline, antisocial, narcissistic)personality disorders. From all the lurking I've done I can definitely say I wonder about some of yalls childhood

but then there are some of us who are relatively trauma-free, aside from the usual mental wear and tear of life. Which brings us back to genetics lol
If any of my fellow nerds wanna read the studies I can send links
