As I write this I'm still coming down from my first ever Super-O, nerves are still on edge and my hands are a bit jittery. Roughly two years ago I began my journey with the Aneros Helix-Syn. I've had many breaks, and have probably only used it for maybe 3-4 months, at spurts of 2-3 weeks at a time. I'll try to catalog everything that occurred during my session first as I think most people are interested in that. Afterward I'll go into my preparation and events leading up to this. I have a very "engineering" approach to everything I do as such this may be a bit detailed.
I coated the helix syn in a very thin layer of vaseline, the way I accomplish this is by just globbing it on to ensure an even and full coat, wiping my hand off, then removing the excess with a clean hand until it's shiny and slick. Next I internally inserted 5cc (5ml) of astroglide sensitive skin gel. I have a sensitivity issue with glycerin and this is the only water based i could find without it. I then placed a very small amount over the entire length of the toy.
I moved to my bed and loaded up "Dreamgasm" (https://www.youtube.com/watch?v=jK13_DlgFNo). This is actually one of my least favorite of the 5 in the series, i find some parts annoying, but its also the one I had my now second best experience with. Earbuds in, lights out, roll to my side, pillow between the knees, one under my head, one cuddled in front of me.
