I've always attracted a pretty diverse group, not to say a ton of people have been attracted to me (that I've known of, at least), but just different people. I've definitely noticed some patterns, and I try to find the connection between these people.
One definite pattern: ExxPs. I guess it's because I am either pretty introverted and a feeler, but if I'm in my shadow type, I'm just like them, and they like both of those types. Also a lot of them like to go after people to find out more about them, from my experience, and I usually respond well to that because I appreciate the interest. I remember a couple ESTPs, an ESFP, and a girl who introduced herself to me and talked to me a while before I had even said a word to her. Later she took the myers briggs test and got ENFP, so I'm not sure what exactly attracted her to me, but it's definitely a testament to the INFJ-ENFP thing. Too bad I didn't get to spend much time with her, she was hot.
Women of color: There's some kind of connection here that I have trouble explaining, it could be cultural similarities or personality type oriented, but I notice I have a higher attraction rate with blacks, Asians and hispanic girls.
Usually I attract feeling types, partially because most women are feeling types, but also I'm not very theoretical and that probably projects. If they're ESTP or ENTP I can deal with it because they're fun to me and have Fe which is noticeable enough to mistake them for feeling types. Otherwise most thinking types are best as friends for me, I think.
