These types of questions always pop up in sibling incest media discussions and circles but from what I've seen the real life counterparts have little to nothing to do with the person's preferences. Normgroids say shit like "they like it because most of them don't have siblings!" but on /calg/ as well as many other platforms it's always like fifty fifty, in fact I remember the majority here had siblings at some point (this info comes from the censuses). It really isn't related heh at all it seems desu. Pic unrelated.
