Readers make no sense, lol. Often the ones who take the time to review, aren't in the majority. It struck me today: frequently what repulses us in reality does indeed attract us in fantasy, i.e. incest. At its root, incest is just - so wrong. But when reading fanfiction, without the "realness" of the characters, even I will openly admit that Wincest or Twincest is quite adequate for heating up a frigid day amid this despicable polar vortex thing.
Write for yourself; what you enjoy. Screw the rest.
