Helix vs Progasm?

I bought the helix last week and I’m not feeling much in terms of prostate stimulation I’m familiar with aside from the initial insertion. I’ve used it about 5 times so far for at least an hour, my longest session has been around 4 hours.

I’m sure I need my more practice, but I’ve noticed some comments saying the helix doesn’t quite hit the same spot that the programs does. Could anyone help me out here? 🙂
