I use she/they pronouns, and it might be different for others but I identify as non-binary, though I'm mostly femme-presenting. I generally prefer they/them pronouns, but as feminine pronouns don't give me discomfort and I've been using them most of my life, I continue to use she/her as well. It usually depends on my comfort with a social situation, or how I'm feeling on a day for which pronouns I use. I introduce myself with both, and most of the people in my life use them interchangeably for me.
