"Selfies" were not a thing when I was a kid because film cameras didn't have digital screens you could look at while aiming the lens back at yourself. Cameras were big and heavy, even snapshot cameras. You needed a well-paying job to afford regular photo prints and negative development which, as a teenager, I did not have. I had a job, but photography was not a top priority for my spending habits.
Most of my photos from my early teen years were school portraits or big events that included family (because someone else had to take the picture, and most kids didn't have their own cameras so it was the grown-ups taking all our pictures), so I was dressed fairly conservatively. If I took photos of events that were free of my familial influences, my mom still would have demanded to see the photos when she drove me to pick them up from the developing station. Plus, there were all kinds of cautionary tales about film developers making illegal double prints for their own private spank banks, so we just *did not* put most of the shit that we did on film.
If you go back and look at those few photos of me that exist from that time period, you might not have guessed that, at age 14, I had thigh-high stockings and lacy underwear and a mini skirt that didn't cover my ass when I bent over (still have that one too) or that most of the time I walked around with the flannel shirt I left the house in tied low around my waist to show off my awesome abs highlighted by the barely-more-than-a-bra crop top I was wearing in some neon color.
Just because photographic evidence of the past is low, it doesn't mean we weren't still doing the exact same things that teens have always done - rebel against authority, swear, eat food we're not supposed to, and explore our sexuality.
This picture, btw, is of me at age 11. I still have that bikini and wrap too.
