Japanese style bondage anyone?

I'm just bored tonight and was wondering how many hobbyists or providers have tried doing Kinbaku or Shibari? Basically Japanese style bondage. After looking it up I believe both terms mean the same thing. I'm surprised I never got curious to look it up before after finding out at an early age what bukkake meant and telling my friends I would bukkake their moms face. lol. Anyhow, there also appears to be many other names for it. I've stumbled upon a lot of videos over the years and was never interested until recently for some odd reason. It just looks awesome. Especially after watching some videos which make it look really pleasurable for both people. Some of the other videos not so much. Most are pretty extreme and looks brutal for the women. Well I was just wondering if any of you have tried this and how well does a provider need to know somebody to be comfortable doing something like this? Do any of you ladies find this intriguing?

Here's a good example of what I'm talking about. This video pretty much got me into it!
