Greetings!
NOTE: This is by no means a full tutorial---just some helpful tips
When we first started to "play" we discussed what turned each of us on and what was a definite "NO". Surfing various bondage sites gave us quite a few ideas. You can get an idea of a checklist at
http://secure.rosybottom.com/partner.php some checklists can go into minute detail. We also talked to a local Dom/Domme couple for assistance. And an awesome place to start is
http://www.bedroombondage.com/bondageu/index.html which gives some good tips and pointers.
Being on the large size, there are things my wife cannot do such as no tying the elbows together behind her back. Also, even if I had access to something to safely lift her weight[i.e. an auto shop engine hoist], I would never attempt any suspension---KNOW YOU LIMITS AND THOSE OF THE "VICTIM"
We are fortunate to have a basement to our house with very sturdy framing we can easily access. Drilling a few holes and securing some sturdy eye bolts gives great attachment points for chains and rope. Anytime I secure her hands above neck level I always use our quality padded leather cuffs which are worth the extra money. Also, for any load bearing rope I use nothing narrower than 3/8 in=1cm---anything smaller can cut into skin and kill circulation.
Settle for a non bondage sounding safe word---we use "cabbage"---that way she can beg me to stop all she wants to get into the roleplay spirit.
If comfortably tied, she has stayed that way for over an hour just wiggling around in her ropes[but do check in regularly]
Hope this helps
