I have been doing self-bondage for a long time and would like to give you my advise (some learned the hard way).
I use chain,locks, handcuffs, shackles, etc because the bondage is real and wont cut off the blood flow if done correctly, I dont use rope because it can tighten and numb your hands and feet.
1) never tie anything around your neck.
2) when using handcuffs make sure the key hole is faceing your hands.
3) use locks that have the same key.
4) never use fire or elect in your sessions.
5)always use backup releases, never trust one release!!!!!!!!
6)if you going to use a gag, make sure you can handle it for the time you in bondage, (try first unbound for 2to3 hours).
7)wrap duck-tape around your wrists to cut down the chaifing.

9)if you can, double lock the handcuffs so you dont tighten them in error.
10) dont cuff your ankles to tight (you wont be able to walk).
11) Before clicking that last lock in place make dam sure you checked everything at least three times.
In closing I know how exciting it is to dream up a new session, and when your horrny its not your brain thats thinking, its your cock or in my case its my cunt and you tend to rush into the scene, please stop for a second, and make sure your safe.
I am not your mother! but care abought you all, and would hate to see anyone hirt.
PLAY SAFE..............HAVE FUN
