INTJs don’t value sex and physical affection, at least not on the same caliber as most people—inferior Se and demon Si. Like ENFPs they live in their head but are highly focused and dislike expending energy. Highly verbally and physically affectionate ENFPs will find them too withdrawn, unresponsive and dispassionate. They’re also very slow and avoidant. Blind spot Fe, so don’t give a rat’s ass about people and have little tact, unless for a specific purpose. It’s also a position in a stack where they place no interest in improvement. Much of that ENFP-INTJ myth comes from the proportion of mistyped ISTJs. If your boyfriend is dependable, perfectionistic, physically organized, and affectionate, that’s all signs of Si-valuing. They plan a lot for the future too.
