A, first of all Nicole's anal scene in episode 3 it depend on status and not affinity, Before you gain Permanent Affinity, you actually can be Chick affinity and still be a Huge Dik, once permanent affinity kick in, this is no longer alowed, you can only go as far as having Dik status or Chick status and only as a Neutral Affinity.
B, in the latest episode, Nicole has a scene during her lewd scene, a position that only available, if you are Chick Affinity confirming that Nicole is actually a Chick Affinity girl, Along with , Jill, Bella, and Maya.
DPC loved and still loves to mess with the Player with his precious consistent Affinity system.
Like Lily for example, in episode 5, you can't get free blowjob from her if in that moment you have Dik affinity , but in episode 7, you can fuck her if you have Dik affinity even if you did not get the Blowjob in episode 5.
The guy is super consistent, but remember it is not about chasing various stats, he would not want that from player, you just " follow you heart "
