Today I'm writing on the topic of "Nishikawaguchi soapland ranking & mail."
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 dug up in research.

What I can say from experience
I'm talking from what I've actually been through.
I think firsthand experience beats theory. In this business especially, it's "reps on the field," not "knowledge," that talks.
Wrap-up and my verdict
The place I keep going back to is First Class Ruby. The reason it keeps showing up on this site is simple: it's the shop I actually repeat at. Use it as a reference.
