Hey, welcome.
I would not rule out the possibility of you being
LSI too prematurely. LSI has got
4D Si, so it is not impossible for them to mistype as SLI.
Your description of yourself rather reminded me of an LSI (esp. the "
I seem like a jock but am also secretly a nerd"-part. Most Beta STs, esp. LSI, relate to this. Maybe @Myst can give her own perspective on this, and how she figured out she was LSI and not SLI.)
Just a heads-up to make sure you don't settle on a possibly wrong type too quickly.
Good idea would be for you to reach clarity in regards to
Beta vs
Delta, find out which Quadra feels familiar.
Also, whether you "like"/enjoy
Fe or
Ne more, especially in other people.
E9 could be about right, but check up on
6w7 to make sure this is not your type, for it is another possibility.
SO blindspot is rather likely.
