Hello, very new, learning, never been locked up, though as a submissive CD I doubtless should be. I'm using my CD name on this site, but on FetLife I'm using another name which I probably should have signed up for with my CD name, which is because I'm new in some ways to these sites.
Welcome to the Mansion! If you're interested in chastity then your best course of action is to buy a device or two and start self locking. Plenty of forum discussion on how to pick and size a device. If you need help, ask!
