Eupho and Helix p-tab never really touches

With me they do touch down there, but since the arms are flexible (too flexible?) I never really feel any pressure on the area.

Dont't estimate the P-tab. I don't feel it either but I think it has a function under the sessions. It do touche the perineum but more gentle than the older models.

I agree with amaz... My Helix Syn P-tab definitely touches...I do have to periodically adjust it in session to get it on the right spot...it definitely digs in when highly aroused and experiencing orgasms...but as amaz says...it's not uncomfortable and definitely adds noticeable/pleasurable stimulation to the perineal sweet spot.

I have the Helix Classic and if it's in all the way and aligned, it hits the spot perfectly.

A newbie here... I have been using Eupho and Helix Classic for 3 years and it's quite the opposite for me, they get immediately all sucked in, like really hard, P-tab is dug in deep and no movement at all.
No involuntaries, nothing.

Then you all are bigger guys, this is why smaller devices are better for smaller guys. See now?

I'm the same; my Eupho and Helix tabs never really touch unless Im contracting or sometimes late in the session they "nestle" into a touching position. I've also had this problem with my Vice, however My MGX and Progasm tabs immediately touch.
