I have been into BDSM for 40+ years now and have by and large enjoyed the journey. I've been lucky enough to experience many of my fantasy's. One regret I have is that due to circumstances I have never been able to experience an intense, extended (24-48+ hour) CNC captivity type session like I discussed in this thread some years ago.

I realize as I age through my 60's the chances of me ever being able to realize this are becoming less likely. Although, I still hold out some hope.

I'm curious if others have similar unrealized desires in BDSM they regret never achieving or perhaps it's something you did manage to experience but now regret?
