I think a lot will depend on when you started you periods. I was born early '70s - we had a school visit from the Tampax lady when I was about 10. At that time, the choice was only tampons or pads.
My mother was prepared for me and my sister starting and she left me in the bathroom with a selection of pads and tampons, saying to call her if I needed help, and reminding me I did a lot of swimming. She'd always left her own box of Tampax by the loo, so I was familiar with what the leaflet said, and I got on with Tampax minis, and never really had a problem with them. My sister turned out to be a pad girl, at least at the start.
Although thin pads were starting to be available, they weren't commonly available till later in the '80s, and pads were uncomfortable. Now there's the choice of thick pads, thin pads, pads with wings, organic cotton pads, gel-filled pads... Not to mention menstrual cups and period pants, but they've only been available for the last decade or so. Girls today have more options than we did back in the '80s.
If there's any pressure these days, it's more about reusable than tampon vs pad, but I don't have a teenage girl to know what they experience these days. I don't remember any pressure at school, or even much discussion. Early on, there were a few discussions about whether you had started yet, but then not really anything till about 15 and occasional panics about someone being late (there were a handful of pregnancies), but nothing about pads or tampons. Maybe I just missed it all, or it wasn't a big deal in an all-girls school.
These days, I mostly use a menstrual cup, but I do often back it up with a pad at least on the first couple of days, because there's a lot more blood to deal with than 35 years ago. I never really understood how much things would change over the years, either - I don't know if I just ignored it as irrelevant, because when you're about 10, anything over 25 or so is basically so ancient you're almost dead, or if it wasn't mentioned - I suspect mostly the latter, because the focus was on what happens to your body through puberty which will happen soon, not stuff for decades' time. I hope these days girls are told about all the different options for period protection, but I get the impression at least for some women, what they learnt about periods growing up was less than we did in the '80s, and it's difficult to make informed decisions if you don't really know what's going on.
