Queersync is the phenomenon of consistently and unconsciously gravitating towards other trans/queer individuals in one's life, despite not knowing or recognizing their shared identity until later in life. This term can be used to describe the feeling of serendipity or resonance that comes with discovering shared experiences and identities with others.
I started to realize the queersync in my life - many of my closest friends and past partners also identified as trans, even though we didn't know it at the time.
