I understand it this way. Many of us have Gender Incongruence, and this is when our identity doesn't match our perceived birth sex. We all perceive our gender identity differently, and the more we align with our own identity, the less dysphoria we feel.
Many of us have a vision of what we should look like, and if we can match that vision, we will have reduced our dysphoria to levels we can live comfortably with. It seems like you are in this group. I am in another group, less concerned by my appearance and social acceptance, but possibly my vision is more about what I am inside. I didn't seek physical or social transition, but I did have a big dysphoria trigger with my genitals. GCS dramatically reduced my dysphoria, so much so, I suspect if I could have had GCS initially, I might not have needed to socially and medically transition and would have been happy living as a male.
So if you are in a place where you don't have significant stress for your genitals, it would only be for practical reasons that you might pursue GCS. Sadly, many of us look at other people and impose their expectations on ourselves. Just because other trans people get GCS, it doesn't mean that is right for you! Think about why you are considering surgery, and what is right for you.
For example, I had no desire to get breast augmentation. I have an issue with having foreign material placed in my body to feel more 'me' ( this is my hang up, I don't impose it on others! ). I had one B cup and one A cup, and this was making it difficult to buy bras. I was regularly being misgendered (which didn't overly worry me), and a trans friend persuaded me that my life would be better, for practical reasons, to get implants. I did, moving up to D cups, which better suited my frame, bras were easier to find, and I was misgendered far less. In the end, augmentation worked for me, but it had no effect on my dysphoria.
It's so worth working out what you need, and why, so you make informed decisions on what is right for you.
