cock and ball splitter

just bought cock and ball spliter for hubby ,,loves it when on but he says his balls feel like a burning sensation is this right ?

hi my i just quizzed my partner and he says he has never felt burning so that type may not suit?

doesn't sound right - lots of gay guys use them and i've never heard of this problem from any we know.

What exactly is a cock and ball splitter?
Excuse my naivety.

Nice to the see questions don't go unanswered.

could just be the blood filling up under restraint
