I could easily see clashes of ENTP and INFP. I often think ENTPs misuse their abilities and hang around with ESTPs and ESTJs so that they do lots of shit.
While one ENTP I know always tells me I should use my abilities more often.
funny, when i'm around ESFJ's i'm incredibly perplexed.... it's really entertaining... but i'm sure if i was to know one really well, we'd begin to clash... the ones i know always have to talk about.. stuff.. and how well they did on this/that... and how i should wear my hair. it reminds me of being around kids who are just kind of in the moment... and that can be nice... but when they get pissed off, it's not so fun.
Ime, I usually get along brilliantly with NTJs, usually male better than female. Male INTPs and STPs I can have a blast with, but it's more superficial usually. Get along grand usually with female NFPs.
Male ENTPs and I tend to clash, female ones less so. I can totally see INFPs having trouble with ENTPs, I don't blame em. SJs usually stare at me in bewilderment or disdain. I don't really have strong feelings towards them usually. Female XFJs tend to wanna mother me or 'teach me'. Can be annoying but I can appreciate it for what it is.
I wish I were better able to type my friends and family.
I do know that I have two close male friends that are ENTJ and INTP and I get along wonderfully well with them. Under different circumstances, I could very easily see either of those being romantic relationships. They both seem to get me and when I go somewhere with either of them we really seem to have an us against the rest of the world attitude. I suspect this may be true with INFJ and many NTs...though I have met a few that I can only take in small doses.
My best female friend, however, is ESFJ. She doesn't get me quite the same way they do, but we have known each other since kindergarten and I really think that makes up for a lot. She and I tend to complement each other...I had quite a busy social life in high school for an INFJ and it was mostly due to her influence.
My closest relationship is with my ISFJ boyfriend. I am really, really surprised at the level of intimacy we have. I know this is not "supposed" to work so well, but it really does. Maybe it's the shared Fe and Ti? I don't know. All I know is S or not, he really gets me...probably more than I get him...but that's ok.
