tape yes
But NOT regular tape
get: Medical tape
it is very inexpensive
and avaiable in pharmacies (at least in usa) and some other stores
to help you know What you are looking for:

It is hypoalergenic.. designed to go next to your skin
and waterproof so you can leave it on a while.. weeks even without difficulty
Yes I have tested it.. the tape that is.
Usually you can wrap a little after device is on.. or.. just before
You can rip it.. in half at the "joint" so when the ring clips the tape ..buffers you a little.
you may need more than one.. layer.. sometimes it takes 2...
If this does not solve your problem
frankly.. you may have gotten the wrong cage...
also feel free to milovana Mail me.. about problems.. have worn several cages
so am usually fairly good at problem solving/ offering suggestions.
