I bought my helix some time ago and had very little success in my first several attempts. It sat unused for several months. Last night I got it out, cleaned out my rectal canal really well and spent time just relaxing with it in place. I lay on my side for a while, did the recommended deep breathing and got comfortable with the helix in place. I delayed contractions for a while too. Still not much happened in the way of sensation.
I then rolled onto my back and put my feet flat on the bed. I contracted the scphincter a few times and then lay still. Quietly, waves of delightful sensation started to build. I held perfectly still for fear that movement might break the spell that was coming over me. I don't think it actually lasted that long and it wasn't a body wracking experience but it was like nothing I've ever experienced before. As the sensations subsided I contracted a few times but the whole experienced passed.
Nevertheless, I take it as a first success. If I can duplicate and intensify that sensation over time, I'll be very satisfied. I feel like I've crossed into a new frontier of sensation that I've never experienced before, in many ways similar to the first orgasm I had in my early teens.
I'll keep this forum posted.
