My take on the gq4gq flag
gq4gq (or genderqueer for genderqueer) is for genderqueer individuals who prefer to or exclusively share encounters and/or relationships with other genderqueer individuals.
cisn't4cis't
cisn't4cisn't is for cisn't individuals who prefer to or exclusively share encounters and/or relationships with other cisn't individuals.
I made this as an alternative to t4t for those who view themselves as neither cis nor trans and for those who don't only prefer to or exclusively shares encounters and/or relationships with trans people but also with those who are not cis but not trans.
nb4nb
nb4nb (or nonbinary for nonbinary) is for nonbinary individuals who prefer to or exclusively share encounters and/or relationships with other nonbinary individuals.
xen4xen
xen4xen (or xenogender for xenogender) is for xenogender individuals who prefer to or exclusively share encounters and/or relationships with other xenogender individuals.
All of these flags are based on this t4t flag.
