Today's topic: "fuzoku, lovey-dovey, Koshigaya."
I'll explain it by mixing in my own firsthand experience from 20-plus years in fuzoku (Japan's licensed adult-entertainment business) with what I've turned up through research.
The basics
Let me lay out the fundamentals you should know about this area.
Watch the industry long enough and you'll see that even on the same topic, the "customer's view" and the "girl's view" can rate things completely differently.
What experience has taught me
I'll speak from what I've actually been through.
I believe experience beats theory. This industry especially is one where the number of times you've been in the room matters more than "knowledge."
Wrap-up and my verdict
The place I keep coming back to is First Class Ruby. The only reason it shows up over and over on this site is simple: it's the shop I actually repeat at. Take it as a reference.
