Also in my experience, the 4 is very silent for the 3w4. They seem like just 3's while the 3w2 seems like a 3 with a wing 2. If you can feel your uniqueness then you're probably a mistyped 4w3 and judging by the fact that you're a male, it's not surprising. Men usually want to be 3's or 8's.
No. Those are the 4w5s. 4w3s constantly think they're 3s cause of the shitty 4 descriptions that cater mostly to the 4w5s. It's always been the 4w3s and 3w2s that have been linked to narcissism not 3w4s.
Enneagram is about motivations, not behaviour ! Absolutely nothing tells 4w3 and 3w2 are supposed be more overtly narcissist than 3w4 (where the hell does that comes from !?). And men want to be 3 !? That's completely new to me. 8, yes (and I know several self-typed 8 who probably are 3) but usually, people want to be 4 and even 4w5, 4w3 being viewed as 3 or 7 (or even 2w3), and 3 being viewed as some sort of narcissistic pervert.
3w4 can feel some sort of uniqueness, having a 4 wing.
3 and 4 are both image type, they create an idealized image in order to compensate their self image, that is primarily negative.
The difference between them is that 4 (yes, even 4w3 !) always fall short, while 3 (yes, even 3w4 !) identify with this idealized image. Thus the passion of envy for the 4, and the passion of deceit for the 3.
3w4 can be very narcissist indeed in that they believe in their idealized identity. As this identity fits what pleases them, they are assertive, and when unhealthy, the gap between what they believe they are and what they really are can be big. And the narcissism shows. I'd say this is especially true in 3 So, who wants to be seen as successful, less so with Sp (and even Sx ?).
With 4w3, there is this idealized image also, but while partially using the 3 mecanism, they always fall short. They are more honest in how they see themselves, thus the drama, the strong emotions. I'd say 4 Sx in general is the most prone to narcissism, as they deny their feeling of inferiority (it's under the surface though, and that's why they are so reactive). But a 4w3 So or Sp may not seem this way, not so blatantly. There is a sort of narcissism in that they still are self absorbed, auto-referencial, fascinated by themselves and elitist, but it usually doesn't come in affirming they are superior.
Usually it's 3 that is associated with narcissism, but Naranjo associates it with 7. As an hedonist with an assertive, positive personality, 7 may think of themselves highly, while not being as concerned by their image as a 2, a 3 or a 4.
As for 2 : I feel that they can be narcissistic as well, as they believe what they do (whatever it is) makes them entitled to be loved. 2's passion is pride and it doesn't seem so far from narcissism.
