Actually I’d agree with the pp who raises a very good point. There’s different types of pride in ones appearance.
Pride in your appearance can be a very good and healthy thing. It’s not the case If you take pride in your appearance you can’t take pride in anything else Ie children achievements etc, you can take pride in many things at once,,,the sort of pride here is about taking care of yourself, being clean, well groomed, healthy, fit, well dressed, feeling good about yourself, any manner of things, and these are a huge positive.
The taking pride in your appearance that’s a negative is when it translates to vanity, showing off, being shallow, taking photos and messing with them and trying to get compliments from people, posing and pouting etc, that’s when it turns to a negative, not just for others but for the person doing it.
Op I think thr issue is your pride in yout appearance is the latter from what you’ve posted. It’s not about you feeling great and secure in youtself, it’s not about candid shots of you, alone, with others doing fun things, it’s about you posing and pouting for likes. That’s bad enough when it’s a young adult but does become quite negative when it’s someone in their forties.
