The only SPs who would be more reserved with new experiences are Fi dom/ISFP, but even then, we rely on direct experiences before thinking whether something is worth our time or not. Relatively speaking, ISFPs seem almost extroverted compared to INFP (we're not though... I know I can start clamping down just like an INFP once I know enough about certain experiences, or ones that resemble them).
Feelings: I explore the darkest corners of my soul!!! I should probably get a trophy for it.
Aesthetics: I'm open to any style/genre..even willing to give artists/directors/musicians I hadn't liked before another chance.. I tend to take individual works on their own. I'm not particularly against any form of expression.. it's bad execution that I don't like.
Intellectual curiosity.. I'm interested in many subjects, but I'm not interested in digging deep into many of them. Give me the cliffnotes version. Every few months however I get a new intellectual obsession, and I try to look extensively into it.
Fantasy: Not really. I like experiencing things directly. If I can't, I move on to experiencing another thing directly. Fantasy doesn't hold my attention for long. I like mulling over scenarios or thinking about what's important to me, but I wouldn't call that fantasy. Even a lot of my creative hobbies aren't imagined beforehand much. I pick up a guitar, and I start playing. If something comes out of it, cool.
I'm pretty much just like this. Except I am a daydreamer and fantasy oriented, as well.
