Hi
I need some advice ,i find with my 2 models Helix syn and the Progasm junior that they both work away from the Perineum area in normal use by about 10-15 mm.
I lay on my back with 2 cushions under my lower back and then insert the device ,very often i find that the device has worked away from the Perineum area meaning the P Tab is some distance from the Perineum ,is this normal or if not is there a solution .
Thanks Dennis
