"Nishikawaguchi, fuzoku (Japan's licensed adult-entertainment business), recommendations" — some people hear that and instantly get it, and some don't.
At 42 I'm still out walking this world in person, so I'll put it together from a real-world angle.
Why this topic matters
Information about fuzoku is surprisingly disorganized. Beginners especially tend to end up not even knowing where to start looking.
What that actually means
Put simply: whether you know or don't know changes the quality of the experience.
What I've written here is the distilled essence of knowledge I built up over 20 years.
