New personality theory based on genders that I invented

[thistle]

That sounds good. Maybe 'null' ?

'null' sounds like a lonely or maybe superficial existence - because it doesn't have an opposite to interact with. What do you think?

Maybe another null? Same with "baby", maybe another baby?

Edit: I'm thinking this is maybe in the third level. I think even though the most likely compatibility match is with your gender opposite, maybe there could be a woman that likes babies for example? Similarly to socionics, what these would tell you is the "tone" of the relationship, like ITR's.
