What are the differences in sensation between the Helix and the Eupho?

I'm sure everyone is different but for me the sensations with the Eupho seem to be a bit more 'focused'. Also, there is a lot more movement with it.
I always start out with my helix. It's the one that just seems to fit me perfectly in there and gets everything started up nicely. The sensations are beautiful and powerful but they seem to radiate to a wider area in my abdomen. Once I start having my super o's and I get super sensitive to every sensation in there the size of the head seems to fill my whole abdomen with pleasure.
Sometimes I stay with my helix for the whole session, but sometimes I will switch to my Eupho. As soon as I do that I notice a lot more actual movement when I do contractions and like I said, there seems to be more of a focused area of pleasure where it meets my prostate. The combination of the pleasure from the movement in the anal canal and the focused pleasure on my prostate is...shall we say ... electrifying. 😉
Quite often I will use my progasm between my helix and my eupho. Of course it takes things in the opposite direction...not much movement and a really lovely full feeling. Then, when I put in my eupho I REALLY notice the movement and the focused energy. The progasm sets things up for my eupho beautifully. 🙂
Hope this helps.

@Spanishguy69, to me the Progasm Ice is for swordplay, the Eupho Syn is for foil fencing and the Helix Syn is for something inbetween. I prefer my foil for this:

Perhaps you'd like to read my blogpost about my Eupho Syn's initiation? But keep in mind, it's only my personal view, it's no competition, it's all only about having fun and find the maximum state of one's own bliss!

The problem with us humans is we mostly wish to have more luck than any other.
A dead issue, particular because we generally assume the respective other is happier than he is.

Therefore savor your personal self-made bliss and you are on YOUR path! Good luck and take care!
