Chastity Cage Dilemma

I have own several cages throughout the years, but I could never really use them, as my clitty is a grower. When I got erected, it can get much bigger and harder than when it's soft, it's a healthy member. Whenever it get erected, it either push the cage out on its own if I don't have the belt, or hurting itself real bad. Yesterday, I ended up with big tears on either sides of the head, and rash on the balls because I refuse to unlock. Like it's protesting saying: that's not what it want. Even though I really like chastity cage, I don't want to hurt myself either. I'm really jealous of people who have small clitty. Just want to empty my thoughts, sorry.
