Is something wrong with my nuts

Hi everyone,

Im new to the site officially, however i always come here when i have a question to search nover previous threads. Today, however, I cant find an answer to my question/problem. So here it goes.

My wife/KH have been involved in male chastity off and on for a while now. The same problem always comes up that stops it for a some time. Every time that my wife decides to lock me up again we make it to about day 3 or day 4. the my left testicle starts swelling up and aches. like a severe case of blue balls, but only in one nut. She always ends up letting me out and relieving the pressure. Its so very disapointing.

My question is if this is normal or not? How do i get passed the pressure? What have your experiences been?

Thank you,
Bobby
