Asking from the point of if it happened to you in real life, if you came home and saw your partner in the middle of fucking a black guy and neither of them noticed that you saw, would you interrupt it? or not? I think even if I didn't have these interests and if it was an actual cheating scenario, I would probably not interrupt it and feel too shocked to do anything and just address it later. I'd do the same if it happened now and feel conflicted feelings, but since a lot of these specific scenarios/fantasies that I have relating to my girlfriend and this interest all have a "cheating" aspect, I'd probably feel a mix of turned on and distraught. I kind of asked a variation of a similar question a few weeks ago, but that one was more general. I wanted to kind of revisit it and narrow down the choices but still want to open it up for a detailed answer and discussion from you guys.
