Today's topic: the ekiben position — how to do it, the cautions, and the tricks for making it feel great.
I'll mix my own hands-on experience from 20-plus years in fuzoku (Japan's licensed adult-entertainment business) with what I've dug up through research.

I believe hands-on experience beats theory. This industry especially is a world where "reps" matter more than "knowledge."
Wrap-up and my conclusion
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 the shop I actually repeat at. Take it as a reference.
