I'm not aware of having of ever felt a strong attraction to SJs. In fact ESxJs are the type I like least and that is basically in the realm of impossible. I'm not sure why, but I notice a pattern of ISFPs having interest. Now that I think of it they also either tested as enneagram 9s or it was just my best guess. From what I've read 9s like 4s but I'm not sure. I haven't noticed any particular reaction with ESTPs except for only one that I worked with was older than me and told people in the office he had a huge crush on me. Well it was just kind of weird because we seemed so different. Other than that I get a vibe ESTPs find me boring or something similar. I find NTPs attractive.
