A question for Shingo Lee. In your column, you wrote:

I’m Shingo Lee, a columnist. This isn’t a source of my own knowledge, but one book I’ve recently found worthwhile is *Yoroshiku, Your Sex*. I believe imagination is more important than having the “right” knowledge, and I liked this book because it’s full of content and illustrations that spark the imagination. Since it doesn’t explain why each technique is effective, people who prefer a more logical, evidence-based approach might find it lacking. Still, it’s a good book that makes you think, “That’s not really what sex is all about, is it?” There were also many approaches in it that I already use, as well as plenty that I’d like to try. I’ve never heard of the Tori method, so I can’t comment on that. As for portio development, I’ve read Yamayura’s *Vaginal Sensitivity Development and Internal Orgasm Manual*. It’s the book that popularized what’s commonly called “external portio development,” but I’m opposed to this simplistic approach. Preparation is necessary—relaxing the body, increasing blood flow, and creating the right atmosphere. I’m concerned that people are skipping all of that and spreading the misconception that external portio stimulation is automatically pleasurable. Well, since I’ll inevitably have to say, “For details, see the next pleasure process,” in future articles, I’ll leave it at that for now.
