#nonbinary titles

Yes! You can also use:

-your title or job (ex: Tr for teacher, Dr for doctor)

-M (short for mist instead of mister/mistress)

-Mm (short for mistrum which is the gender neutral versus of mister/mistress)

-Ind (individual)

-Per (person)

-X (like mx, but without the m)

I think the most common is Mx. A couple others are Misc. and Ind. Here is a Wikipedia article detailing these 3.

I’d talk to them about the name thing. They might be comfortable with boyfriend or girlfriend but they might prefer partner, or something else; it depends on the person.

About the sexuality. I’m not 100% sure. When you entered the relationship you thought they were female so I guess it still makes you homosexual. Technically I guess you are pansexual, but if you aren’t normally attracted to non binary people as well as binary then you could still call yourself homosexual. If I’m wrong please correct me!

For titles, the only thing I could think of off the top of my head was Mx, and that some countries will let your legal gender be X (instead of M or F).  But I googled it and there’s this handy list of neutral terms to call people.

As for explaining it, I’ll just tell you what I tell people for my feelings that they seem to understand.  Sometimes I feel feminine, and want to wear lipstick and a cute bra and be noticed as a girl.  Other times, I don’t feel feminine, and want to curl up in the middle of my bed, covered in blankets, just quietly existing.
