I think that it is very arbitrary honestly. What kind of things constitute you? What are you? How are you defining yourself to be?
Preferences and aversions are a consequence of causality. It is not like we were born choosing this or that, some things were already chosen for this "body-mind", and the psychological construct of "I" took hold of that automatically, but in a certain way, I think it doesn't matter. There were all just my ramblings when I was trying to explore the "self" from a spiritual point of view, so don't take them seriously. I think that truth goes deeper than this.
From my experience, it seems that the "I" is a construct that tooks hold of experience. It appropiates everything around an illusory actor that was never there, but on which a story is created to construct continuity and rationalize explanations and narratives regarding identity. I honestly think that at the end it doesn't really matter, because there are attachments that are harder to break, and cause a lot of suffering because the conditioning that gives rise to the experience of suffering is supported by thousands of causes and conditions that make it hard to not suffer. For example, for some men, leaving behind the idea of never getting a girlfriend might be easier or harder, depending on the present conditioning.
The thing is that it doesn't matter to investigate this, because "you" or better said the body-mind, it suffers because the things that it is conditioned to search cannot be obtained in this life.
