How are people asexual?

I'm curious to understand, how does one identify as asexual? Is it a choice or a natural orientation? How do asexual individuals navigate romantic and sexual relationships, given their lack of sexual attraction? Are there any common misconceptions or stereotypes surrounding asexuality that you could help clarify? Additionally, how does society's sexualized culture impact those who identify as asexual, and what steps can be taken to create a more inclusive and understanding environment?
