Finally beginning my journey into chastity

Hi all, My fiancée and I have decided that we would love to start exploring chastity but after doing some reading I’ve realised there is a lot more to than simply putting on a cage . I know it was probably naive of me to think of it as simply that but after doing research it has made me even more excited to start this journey . Anyways I was hoping I could simply get some advice as to finding a cage that would fit just right I’ve read lots of stories of guys finding it uncomfortable and leaving them feeling raw which I something I would obviously like to avoid. I was also wondering if anybody else before they started getting into chastity was worried about how there other half would feel about it. I just worry that once she’s sees me like that I can’t take it back even tho she seems really keen and excited about the prospect of it and as you can tell by name she’s really looking forward to incorporating it into other areas of our play Sorry my first post is so long I just thought this is the best place to ask advice, thanks for any advice in advance .
