Kio Was Only 10 Years Old When He Started Drawing Hentai/Porn

Kio feels proud of saying that he was drawing hentai/porn for 14 years, and currently, he is 24. Question is, "Why did he start at such a young age"? Of course, children do not draw anything like that at all, unless if they have experienced some kind of porn, which is illegal to do. Who could of influenced him of doing that anyway? Could it be his parents perhaps? Or what about any of his friends? He never mentions that at all, so he keeps showing off that he practiced for 14 years, but at the end, he grew up drawing porn. Where are these so-called drawings anyways? There are just a few dating back from either 2006 or 2007, but you don't really see any dating way before that. Is he bluffing or does he really mean of what he says?
