I am an ENTP, 4w3 sp male. She is an INFJ, 2 sx female.

I've just started learning enneagrams, so I don't really grasp the significant of what I wrote down. So could someone be so kind to give me an idea or reference of what I just described? I understand all the ENTP-INFJ dynamics, but not the enneagrams. So someone please tell what the enneagram dynamic is here. Please.
