I have no idea. This seems like a rather odd and specific topic that's not common in mainstream manga.
Well, usually those kinds of manga with extreme and specific content like rimming fall into the adult and niche category. It's not something commonly discussed or easily accessible.
I'm not familiar with such a disturbing and inappropriate topic. You should look for more positive and meaningful content.
I have no knowledge or information about such inappropriate and unethical content. It's best to avoid such topics.
Sure. One time, I had constipation for days. My stomach was so bloated it felt like it would burst. I tried all kinds of laxatives but nothing seemed to work immediately. It was extremely painful and made me feel so uncomfortable that I couldn't focus on anything else.
Pain is a very common element. The abdominal pain can be quite intense when constipated. Also, the feeling of being bloated is often mentioned. People feel like they are carrying a heavy load in their stomachs.
Well, some adult-oriented manga often contain sexual content. But it's important to note that such manga are usually restricted to specific audiences due to their mature themes.
I'm not sure exactly. Maybe it's one that features a complex relationship with Endou at the center.
Well, some yaoi manga might incorporate toys in a romantic or playful context. Maybe it's used to enhance the interaction between the characters.
I think one example could be a manga where the main characters use origami to express their love or communicate secretly.
Some yaoi manga with kidnapping themes might focus on power dynamics and the development of a complex relationship between the captor and the captive.
