Shibari and Bondaj

[Shamanakas]

I have some questions here on a topic in which I am not experienced, but on the forum there may be quite experienced people.
The fact is that my wife loves various types of fixation during sex: bondage, handcuffs, gags. This is not my fetish at all, but as usual I like what excites my partner. Accordingly, I would like to gain more experience in the topic.
The questions are:
1. Shibari. In what position is it more comfortable to have sex and what is the best way to knit for this? Or is it better to separate shibari and sex entirely as related but separate things?
2. Deprivation. Gags, bandages and so on. Who likes it and how to enhance the sensation?
3. Handcuffs and stuff. What is the difference in sensations with simple handcuffs, fixation to the bed, and shackles (rod?).
4. Which of all this can be used in the opposite direction on a man?
