First of all, the MBTI officially used to report "x" preferences, namely preferences in between the two extremes of a dimension, originally when Myers allowed omission instead of a forced choice format.
The MBTI is strongly convergent with the Big 5, and all the analysis done by Big 5 researchers suggests one should consider some middle road preference possibility -- one option being to reinstate x's for the middle third of the distribution.
This doesn't mean you have no preferences, merely that your preferences on different themes of the distribution may go in distinct directions. And really even from a Jungian standpoint, this is hardly surprising -- not ALL aspects of Feeling are opposed to Thinking -- they're more like mutually irreducible complementary poles. But for instance, one can feel the value of a great logical idea, as compared to a mediocre one, and that helps.
If you consider yourself neither a somewhat coldly impersonal logical person, nor someone who is predominantly given by their feelings and values depth of feeling over logic, then perhaps you're neither a T nor a F.
Also keep in mind in terms of the functions, some aspects of the T vs F dichotomy overlap with Jungian thinking-feeling, but T-F is much more Agreeableness tinted.
I for one consider myself higher in F than I do in Jungian Feeling, despite typing myself both a thinking type and a T. Jungian Feeling has a focus on value-judgments, and all feeling-reactions, not just kind, tenderminded ones.
