My jawline does not have any structure, it doesn’t look masculine. My chin and my neck have no gap. From a front profile you wouldn’t be able to notice it, but from a side profile it’s very noticeable.
I call it small jaw syndrome.
Once you have become aware of something on your body or face which you personally think is out of place, it starts to obstruct everything else in your life and that specific thing takes over. I remember looking back over my wedding photos and not seeing how special the day was but my chin- or the lack of chin in my pictures. It made me feel insecure.
