I used to flinch a bit when my lovers device came off and there were visible marks left by it. I didn't like it at all. I thought it was ugly and painful looking and I felt responsible for them. Now all these years later I feel differently about it. I don't know when it happened. It just did. They look to me like marks of devotion now. Some are visible while a device is being worn some are apparent only when it's off. Some marks fade within minutes after unlocking. Some remain. One of the submissives I coached sent me a locked photo yesterday. Lttle creases were evident in the skin around the base ring. Time and constant wear have pleated the skin there. I found it quite endearing.
