>>5493387sure, but no different than a clothing model. If you've seen modern junior idol gravure its very very tame. It is not like the doujins, at least not in the modern age.
There are also just junior idols, who do not do gravure, and is very unsexual. These are more like "playing celebrity" they dress up, they book shows (usually their parents are managers) and they sing for small crowds of guys at parks and cafes who come to watch them sing. Its merely a hobby and gateway to the entertainment business. And is becoming more popular as the gravure business slowly dies.
