Alma05 I hope once it's on, it'll reduce my desire eventually.
For what it's worth I have worn a CB for just over seven years and I can say categorically it has not reduced my desire one iota. Rather the opposite. By its very presence you can feel something there that is beyond (mostly - ) your reach. This leads to a frustration which for me isn't always unpleasant.
But be aware, I wear it out of choice. In other words I have gifted my sex to my partner in the strongest way I could fathom. In return, my partner does not let me suffer. She is very much aware of my needs, understands how frustrating the belt can be and take steps to make sure I am happy. This has a knock-on effect about her own needs which ultimately leads to more pleasure between us.
But that is not the rule on this forum. Girls (and guys) are being kept chaste in a manner that is beyond their control. That control is usually maintained irrespective of the wearers needs and feelings. Even so, some wear willingly, but others wear very much against their will which they tolerate for other reasons. However, I imagine most wearers will agree with me that wearing a chastity device will not reduce your desires - and may well make them stronger.
Just sayin ...
