Then you're not INFJ. INFJs have Inferior-Se, and thus find it very hard (and are sometimes completely averse to) getting in sync physically with their environment. ENFJs have tertiary-Se however, which means they find it very easy and sometimes fall back on it as an easy alternative to their auxillary-Ni.
Oh, crap, I missed the "physically", sorry.
It's easy to get in sync emotionally. Not physically.
By the way, could you describe Se? The descriptions I've seen are contradictory.

Read the type profiles, "On a Team," and interaction types on this website. INFJ, ENFP, and ENFJ all have very different interaction styles. INFJ is chart the course, ENFP is get things going, ENFJ is in charge just FYI. I would look at those.
