All my adventures are from when I was 18 and over.
Once I started to get the urge to explore my exhibitionist side, I began experimenting with revealing situations. I soon discovered that letting a guy get a glimpse up my skirt or down my cleavage in a staged 'accident' was exciting. The look of surprise, double take, or just a disbelieving stare was enough to get me wet.
At first, I'd slyly undo buttons on my blouse, allowing it to gape, revealing the smooth curve of my breasts, nestled in a lacy bra or, when I became braver, a braless nipple slip. Next, I'd find a quiet spot in a café and sit with my legs slightly apart, showing a glimpse of my panties, shuffling in my seat so that my skirt would ride up over my thighs, showing a little more as I got their attention.
I'd sometimes fantasise about men catching me like that and watching me masturbate as they pleasured themselves, eventually taking things a step further when I became more confident by occasionally going out without any underwear at all so that some lucky strangers would get an unobstructed glimpse of my neatly trimmed pubic area.
One good thing about living in a college café culture is that there are plenty of opportunities for 'accidents.' At first, I walked around the park near my home, where I could bend over quite naturally to pick up a dropped bag or check a lace, letting my short skirt ride up over my cheeks, delighting at the feel of a breeze on my bare flesh, the look of passers-by who'd caught sight of me. But in the end, I found that exposing myself in quiet cafes or bars was the most exciting. It was also much safer for a new exhibitionist, just finding her confidence as it was a controlled environment with staff and other people around me, making it unlikely I'd get approached by some over-enthusiastic voyeur.
