I chock it up to an extension of the teenage identity-seeking socialization instinct that is magnified by internet-style communication. The normally teenage instinct is prolonged into early adulthood along with other delayed adulthood social rites. In the olden days you'd explore your sexuality identity through porno mags or crossdressing alone in your room, or when you go off to college or military or the big city theatre to flirt and party with the cool kids. But now with the internet and tiktok, you can perform anywhere and anytime with no restrictions, it's more open and fashionable so there's all kind of novelties and variety of expressions being celebrated and encouraged. It's a nonstop party that overwhelms "real life" downers like work or family.
