Going All Out: A 48-Hour Self-Bondage Challenge

I found out my wife is going away for three nights and four days in October, so I plan to go all out. My idea is to tie myself spreadeagle to the bed using rope on my ankles and padlocking leather cuffs to the headboard. The key point here is that I won’t use any release mechanism and will start 48 hours before she returns.

I know what you’re thinking, but it’s the only way to truly feel helpless. Any suggestions for other things to add?
