Clicked for me at 15-16 I believe? I had been dicking around on the internet looking for random stuff when I fell upon some, I believe now deleted, tumblr of a girl talking and writing about omorashi. and dang man it was like a lightbulb went off.
See, until I was twelve i wet my pants in public a lot due to medical stuff (and not fun that was nope) and until I got it under control, it was something that I didn't look down upon (it was part of me after all) but nothing I tried to ever really focuss on. But seeing that people (and realizing that I too) found it not disgusting and appealing was both a comfort and a revelation. Then like a few weeks or so after that, I started reading up on it, watching some stuff, getting comfortable with the idea and just
good man good. =)
