As I read through, I went from ISTP to ESTP and finally to ESFP.
ISTPs really like gadgets, functional gadgets that is. Every ISTP has a motorcycle and enjoy sports such as snowboarding.
However, they do enjoy solitary activities a lot, so this doesn't fit perfectly with what you described.
ESTPs love hanging out with people and easily get bored with philosophical conversations. However, they can be really cultural. They value cultural because it is valuable, not because it not necessarily hold any significant meaning for them (as opposite to N culture lovers, who see symbolisms everywhere). ESTPs often see culture as a status symbol (in cultures which it can be seen as such). However, they are not exactly sensitive people.
Which leads me to ESFP.
I believe J people have messy homes, P people have it neat.
