Despite identifying as a BF when I was 15, I did remove myself from the infantilist and furry communities when I was 17, only to return halfway through my 21nd year of life, so I'm actually ignorant of what exactly happens to self-identified TBs as soon as they hit adulthood (however it is defined, I'll say I still felt I was 18, 19 when I was 21) but anyway:
I ask because (since 2009) I've confined myself to 18+ AB places on the Internet (mostly to avoid inane comments and general immaturity, it works!) but now that I'm on ADISC which is ostensibly a "13+" website I'm sensing a higher proportion of teenaged people compared to those identifying as AB.
Even when I was a TB myself in the early-00s I saw plenty of other TBs, and they must all be adults by now, but the proportions aren't the same. I'm guessing they "matured up" and have no interest in infantilism anymore (sparing a diaper fetish, of course) so will the same happen to today's TBs? Or do people continue to use the "TB" label long after they rise into their 20s?
