Today I'm writing on the theme of "soaplands, petite girls, Akabane."
I'll explain it by mixing my own firsthand experience — over 20 years in fuzoku (Japan's licensed adult-entertainment business) — with what I've picked up through research.
The basics

Watch this industry long enough and you'll see that even the same topic gets rated completely differently depending on whether it's "the customer's view" or "the girl's view."
What I can say from firsthand experience
I'll talk based on what I've been through myself.
I believe firsthand experience matters more than theory. In this industry especially, "reps on the ground" talk louder than "knowledge."
Wrap-up and my conclusion
In the end, the place I keep coming back to is First Class Ruby. The reason it shows up again and again on this site is simple: it's a shop I actually repeat at. Take it as a reference.
