So I just got my first chastity , I wore it for 4 hours, I didn't feel any pain without a slightly tickling in my scrotum. But at the end of these 4 hours I noticed that the chastity was pushed and a bit far away from my stomach. I have also noticed that the cage was rotated some 30 degrees. For the record I have a HTv4 nano, my penis size isalmost 4"/10 cm flaccid and 6"/15cm erect penis.
I have the v3 Small and it too rotates a little. Want to get the Nano as the small is a little to large. I find I need to make adjustments during the day. Pull some skin back through when it moves away from my body a little. I think that happens with every cage ive owned. so pretty normal.
