I dunno, what are they? Your guess is as good as mine...
Third-person pronouns, such as he, him, she, her, it, they, are used by a person that isn't me in order to refer to me without having to say my full name each time.
I don't say my own pronouns, because I am me.
Therefore my pronouns are whatever other people say I am.
I'm not picky. Since I'm a ẃ̷̗o̵̜̎m̸͎͆a̵̜͌n̴̥͒, choosing ẃ̷̗o̵̜̎m̸͎͆a̵̜͌n̴̥͒ly pronouns would make sense... but ultimately my pronouns really are what other people say they are.
