Today I'm writing on the theme of "delivery health, photo selfies, Saitama."
I'll explain it mixing my own firsthand experience — 20-plus years in fuzoku (Japan's licensed adult-entertainment business) — with what I've dug up through research.

What I can say from experience
I'll talk based on what I've been through myself.
I believe experience beats theory. In this business especially, it's "reps" more than "knowledge" that talk.
Wrap-up and my conclusion
The place I end up going back to is First Class Ruby. The reason it keeps showing up on this site is simple: it's a shop I actually repeat at. Take it as a reference.
