I dated an INTP a while. It just kind of fizzled out, neither of us had the motivation to really care about being in a relationship. We're still great friends though, and we have some fantastic discussions.
So it's the win for us INFP's! There's something so magnetic about the INTP/INFP dynamic. I'm pretty sure his last GF before me was also INFP. I should add that my first crush was Mr. Spock on old Star Trek reruns.
The INTP males I know seem to catch the eye of mostly NFs. suprise, suprise. *rolls eyes*
I see the most common types as being xNxx and ISFx. pretty broad range and it mostly comes from what I read online. *sigh* There's a lot of complaints about INTP partners and INTP potentials out there. I get torn between deciding whether I should retrain myself or just wear a warning sign.
