I had a fairly unpleasant start – I was 14 and bullied at school for, among other things, being a bit overweight. Eventually the joking about me needing a girdle (this was the late seventies) resulted one day in me being physically forced to put on a girdle. And, once they had photos, I was given the choice of making it a permanent addition to my uniform or see the photos distributed far and wide. So, with great difficulty as you might imagine, I had to adapt to life wearing a firm long leg panty girdle daily under my uniform. They did check on me daily, so I couldn’t cheat. As I was excused gym class on medical grounds, I didn’t even get the occasional day off.
When I left school, I’d got used to being in a girdle after all that time, but I didn’t want to continue. But I had panic attacks when I tried to stop – I guess a subconscious fear of being caught – so I reluctantly went back to it.
I don’t fully crossdress – I tried once, but it did nothing for me and I’d never pass in a hundred years anyway – but I wear a girdle and bra every day.
