My last relationship was with an INTJ with superficially high sensory awareness. He was always pointing things out to me that I missed and had a weird preoccupation with stimulating experiences ... felt he hadn't had enough of them earlier when he should have and was therefore compelled to seek them out but also sort of chicken about it.

In contrast, I'm currently dating an ISTP who is introverted enough, I think, that he doesn't immediately pick up on every single sensory detail. The difference between the two is that when they get down to actually doing stuff, the ISTP just does it whereas it was this whole elaborate production with the INTJ where everything had to be just so. He was way more persnickety and conscious of whether or not he was sucking as much sensory pleasure from the exercise as he could, whereas it's something the ISTP just takes for granted.
