I'm 32 and newly single (yes, it was a factor). From now on, I will make sure to either lead with it, or make it known very early on in the talking stage. It ties in neatly enough with my awareness regarding feminism, gender (in)equality, and so forth. There's no reason to hide anymore, as I feel my genderfluidity (esp. tied in with those things) is a feature and not a bug.
