Se runs counter to the auxiliary function of the INxP, Ne. Engaging in Se related tasks essentially "turns off" Ne, which means instead of relating to others through strong Ne, you will be forced to relating to others through weak Se, as they are both Pe functions. In Beebe's Model, this is the conflict seen between the Parent Archetype (Auxiliary) and the Trickster Archetype (Shadow Tertiary), which deactivate each other. (For Socionics, this is the Creative Function and the Vulnerable Function)
The way to get out of "looping" is to utilize valued extroverted functions if you are an introvert, and to utilize valued introverted functions if you are an extrovert. While using Se would do the trick in allowing you to escape Ji-Si looping, it would be extremely not preferable to the INxP, as that function is both unvalued and excruciatingly weak, even loathed to a point. The more preferable route that won't lead to irascibility and annoyance* would be to engage Ne, as it is a valued and strong function.

being a function that is desperately avoided and acknowledged painfully (or shamefully) when others bring it to your attention.
