Looking for Guidance

I have had a long-standing interest in male chastity. Last night, I finally managed to get my wife considering it. Do you know of any solid threads or other sites that would help show her that keeping men locked up is normal? She had some questions and worries on her mind, which I did my best to soothe. Although I figured she was somewhat submissive by nature, last night she insisted she prefers control rather than submission, so that works out perfectly for me anyway. But any additional tips would be welcome.
