It wasn't a sell. It's an explanation... we talk to these girls all the time. OP asked why, and that's the answer. Most girls are initially hesitant to have anything more than near total darkness, which is not the way we roll. I didn't say AMPs have old women etc... girls are all concerned about their appearance, that's a fact, it's reality. They think red lights hide skin imperfections and darkness makes them youthful. Coupled with a culture of using fake photos as a manor of business and using dark lighting to try and hide that, this style is just something that is extremely prevalent with asian girls... not necessarily because the girls photos are fake, but that's just the way it's been done for a long time and they all continue to do so. For western people, this is more of a foreign concept and not that desirable, which is why we still try to keep the mood while also having enough lighting to keep it bright enough to see what's going on.
We have girls of all ages, from 20 to 33+. If you think Robin, Kitty, Sugar, or Pure are 33+ you're smoking something. But honestly the most popular girls are not the youngest... I think chasing youth is just like a macho thing for bragging rights. At the end of the day a strong connection is more popular.
