If the purpose is to prevent all stimulations.The chastity bra is the second useful equipment,the first one is the chastitybelt.Thigh band is useless.The secondary shield just can be used to prevent masturbation,we doubt this point now.
Story of me and my wife
My wife hates the secondary shield the most,maybe because it's hard to keep it clean.
Those are some consensus we have reached.
I have asked her if I can added some more equipments,she said it depended on my decision.She don't care.
When I asked her if she wanted to be released,she said it also depended on my decision .Then she refused to continue this topic with a little resent.
So it's still difficult to know her real attitude toward the chastity belt.
sun you know her better than we do, but is it possible she genuinely wants you to make the decision and resents being involved?
I am submissive by nature, having my mother in charge of my chastity feels good to me
AlexandrA Both my mothers would like you, haha.
I think you are wrong.
We don't know what your marital life is like, but we assume it's normal, so your wife will have "joys" from time to time and won't have to try things.
Single girls, on the other hand, or at least me, do try, when I'm not wearing thighbands, to try to achieve "something", and something is achieved.
When I'm wearing them, however, it's impossible to carry anything past just below the edge of the shield, and yet anything that goes right under the edge is impossible to move or play with.
I use the bands 4 days a week and the behavior, and even the sensations, change radically.
I don't know if for women with a partner or for girls who have never done "nothing naughty" they are as effective, but for a girl like me (I was never obsessed but I have done things that I shouldn't have 
), yes, they are noticeable when I wear them.

I really don't know the answer.And I don't know how to test some assumptions.
I have thougt I should lock a chastity bra or thigh bands on her body directly to see her reaction.But another voice in my mind told me that may hurt her heart and body.
sun I suppose the question is, do you yourself want her to be in a bra or thigh-banded? And if so, why? Thighbands serve two purposes: the make masturbation even more impossible, and they construct the wearer’s legs. You aren’t concerned with masturbation since she has no secondary shield (and thigh bands would not help,) so it comes down to whether you feel her stride must be limited. And that’s more of a bondage than chastity question.
The bra, similarly, exists only to prevent nipple stimulation and to act as a mental reinforcement of control. If you don’t want one or both of these things, there’s no need for a locked bra.
sun I agree with Renita. Unless you have very strong and specific reason to do such things, it is unwise to test your authority just to see what happens.
