Am I just imagining this or do most jellies hide their gender?

From the beginning I’ve thought most members want to keep their gender private. It’s their preference but , if you agree, can you please give me an explanation as to why this is true? I can’t figure it out. I am out of touch with the youth of today if gender is to be hidden or even denied. “Why do you care?” is not an answer. Sign me, Female Woman Forever.
