I like novelty. Being with someone so similar to me would be boring, so generally if I'm attracted to someone they usually end up being rather strong and assertive yet playful with a nice sense of humor. A lot of the time I'm attracted to INTPs, there is just something so...interesting about them and because they are different from me I can't help but be attracted to them. That being said the INTP would need a nicely developed Fe function otherwise the aloofness would be too much for me and I'd run away.
