If you identify with INFJ so much and have so much conviction regarding typing yourself as such, I would assume you probably are INFJ. These types don't waver much regarding what type they are from what I understand.
Have you considered that maybe your Se is coming out around them because you're uncomfortable? Se is the inferior function for INFJ. That may also be why you have some Se interests as well; guilty pleasures, if you will.
Just my opinion, but I hope it helps!
