Wow, I just browsed your links and fall into a rabit hole full of good inspiration and advice! I updated by
Bondage Ressources with a lot of ideas from your links.
I guess you have already enough ideas and inspiration. Now you just need to pick a tie, you just need some little impulse to actually DO a session, right?
What would you think of a self bondage challenge? I pick a session, we both do it, and based on a variable (e.g. who stays tied up longer, who puts more clothpins onto his body, etc...) wins the challenge and gives the looser a little punishment.
