I think I'm the odd one out when it comes to being 'romantically' compatible with Sensates, introverted or otherwise. As friends, no problem; I have one friend ISTP who I adore and is oddly like me (I have well-developed Ti
and Se). I would also be very unlikely to be compatible with another INFJ. My Ni tells me this.
I'm picky.
INFPs are challenging but I find my INFP 'soul mate' complements my cold Ti + Ni combination by bringing me back from the edge of existential crisis and back to the world of subjective feeling and love.
INTPs would be great, except they can't do what my INFP can do for me and the relationship ends up spiraling into a dark pit of objectivity.
ENFPs are sweet and airy, but too flighty for me (I know this from my aunt and few I've known).
ENTPs are like uncontrolled INTPs (my brother is this).
INFJs are awesome friends to relate to, but we end up disagreeing in the same stubborn way on so many things (my 15 year long childhood friendship with an INFJ has been very dramatic repeatedly for that reason).
INTJs, jesus...they can be good friends but most of them end up hating me before they can get to the point of really knowing me -- the stubbornness of the INFJ with an evil Te twist.
ENTJs -- I believe that's what my aunt is, though she puts on an ESTJ look. We haven't talked in a long time. She'd be good at a boot camp if she got any angrier.
ENFJs, well... if I've ever met one, I don't know who it was. This is where I draw a blank.
I love ISTPs as friends, but ISFPs usually don't make the cut (sorry, ISFPs, nothing too personal). ESTPs are alright, but somehow ESFPs drive me batshit. SJs...forget it on most accounts; I've never gotten along with one beyond keeping the peace as a co-worker.
For me, real attraction (and this is automatic for me on first meeting, whether or not they know their MBTI) seems only possible with INFPs and INTPs. Talk about narrowing it down.
