edit: I'm addressing identity as a whole - not in the context of s3xual preferences.
I am no psychologist - but an engineer. I've noticed us engineers aren't feelers. More often we run our interpretation of the world through logic and thinking first, rather than feelings first.
Some people are heavy feelers and run events through feelings first, especially if extroverts which also means they might look to the external world for validation - and only then run their perspective through the logic domain of the brain.
Neither is right nor wrong; I've noticed feeling & sensor types seem to have 'higher highs, and lower lows' in life.
