I dated an ENTP once and it was very... intense. Had we both been emotionally healthy it might have been amazing. We were those people that couldn't be in a room together without clothes flying and lamps falling over.
This was not always good though, we broke up and randomly ran into each other years later (I was at dinner with my fiance, he with some girl he was dating and we were seated in a way that basically had us facing each other through dinner while our dates had no clue). I refused to speak to him, even when he excused himself to the restroom and made obvious eye contact for me to follow him. He committed suicide a week later.
So, yeah... intense and crazy. BUT if it's healthy, amazing. Just make sure it's healthy.
