I’m really glad that most of the images here are of shibari with the forum thread title, and not kinbaku.
I find that North Americans use the term shibari frequently, and incorrectly, when referring to the more sexualized form of rope binding that is properly called kinbaku. In formal shibari, the one who is bound is rarely, if ever, touched by spectators. The simplest way to explain difference between the two terms is that shibari is purely for aesthetics, while kinbaku usually involves sexual engagement as well.
And if you’ve never tried it, and are interested, there are lots of very good rope masters (often called kinbakushi) in most major cities who have been well trained. If you ever get a chance to see the work done by the late Akira Naka, I highly recommend it. Pure artistry.
Also highly recommend trying it. 😉
