I feel myself very identified with your story, @Tad. It happened to me also at 20 when I discovered mags with fat women.Back in the pre-internet days when I was growing up, for years I thought there was something broken in my because I had no interest in Playboy, Penthouse, etc. Finally one day when I was about 20 I went into a place that was a bit like a comic book shop, but for porn. They had bins and bins of back issues of all sorts of magazines, many of them obscure or short lived. I figured that I'd still find nothing that excited me and then I'd know for sure that naked pictures did nothing for me.
Instead I discovered BUF magazine, as far as I know the first 'adult' magazine to focus on fat woman. I bought two back issues for more money that I really should have spent right then, and only kept them for a couple of days because I was living at home for the Summer and didn't have a very good hiding spot for them. But in that time I committed the stories and pictures to memory as much as I could. I don't remember the names of the models anymore, but I still have a few hazy pictures in my mind.
As an aside, there were ads in the back for Dimensions Magazine, which is how I found my way here once the web had become a thing. So I'm grateful to those magazines for showing me that I obviously wasn't alone, and for leading me to Dimensions which has been so much part of my brain for over two decades now.
Oh no, I wasn't aware she passed away, or that she was even ill. I was a big fan of hers 20 years ago - she was one of the early discoveries I made when learning about the FA/BBW community, too.
