So I received the Syn-Helix only five days after I had got the Peridise set and could hardly wait to have a go with it in a late night session.
Just holding it, it looked like it would be making more contact with everything, and I was visualizing how good it would feel fitted inside me. Was so eager to feel the added sensations the p-tab would have, and also the pivoting effect when the Helix started moving. Surprised by the silicone coating, I actually expected something a little softer, felt more like a firm rubber toy. The texture of the silicone seemed like it would encourage more friction than the peridise plastic I was getting used to.
Made sure I gave myself plenty of time to get acquainted before I had to be asleep. From doing forum research, I decided I would try the vaseline/water-lube approach since thats what I could lay my hands on immediately, and until I could get something better. Turns out to be a very effective combo for use with the helix and the peridise, much better than just the lube alone. Sliding the helix in for the first time was not very uncomfortable, mostly because I was getting used to the peridise, even though there's a lot more of the helix. Inserted very slowly, waiting for the moment when it felt like it wanted to be drawn in, savoring those first sensations. Felt the size for just a minute or two before it became quite comfortable. Walking around the house gave me some new tingles, and by the time I retired to the bedroom for the night it felt like we were made for each other.
