Small, cute, flat, and sweat does not necessarily mean child. I know the origins of the word lolicon, and I also know its usage.
There are real woman, and I do mean woman not girls, who fit Proin's preference. Actually, my brother's girlfriend would probably suit him well. 4'8" cute, and Jewish. I do estimate her cup size to be B however, which may be too large, and her face does indicate she isn't in her teens. She has a T-shirt that says "I'm not short, I'm fun sized", which I find to be funny.
