Oh boy. I wanna chime in here. I've dated two ENTPs (I'm INFJ) and the first one was very gregarious and shy/loud dynamic. He was super nerdy and lacked some decorum. He was kind of crap with his social skills, meaning he'd say awkward things at awkward times, or be really weirdly quiet on purpose. This one was into computers, classical piano. He would get stressed out if he couldn't process my feelings. Seeing him not be able to process my feelings with some idea or respect for what they were was exhausting. We did have a pretty magical connection, nerd-wise, but ultimately, it was complicated in the 'lovers' stage, and he was super needy and...opportunistic. This drove me nuts. He assumed he would like to marry me after probably 6 months of knowing me as a friend. (*ahem* issues).
Now, the second ENTP was also childlike, playful, but much more laid back and more 'introverted', less socially awkward - actually, he was quite sociable with a good social circle, but identified as a 'nerd' (even though he's much hotter than the former haha) and a computer geek who was into video games, sword collections, smoking pot, partying, raves, cheesy heavy metal, having a grand old time. He watched Mulholland Drive and 'couldnt compute' the feelings in the film...had to grab a cigarette to calm down. Even though I found this ENTP way more desirable than the last, I know that deep down, it would not work. When we went to the art museum, he found the spiral staircase the most fascinating thing there, along with the carved figurine of a skull/skeleton..yeah. He found it to be remarkable that I could draw meaning from looking at paintings...so even though this ENTP was super cute, and a nice guy overall, it faded out much quicker - I had a more cerebral connection with the first but more attracted to the second.
That's my two cents on dating an ENTP - sounds great on paper, but in real life...that's the acid test. I think its the E + TP combo that screws it up. The N is great, but the rest can lead to an epic fail, beyond friends.
