Chastity and orgasm denial discussion

I’m currently seeing a fantastic woman who seems to be exactly what I want. During our talks, I discovered she’s into the idea of us tying each other up; it appears she enjoys both pinning me down and being pinned herself, which suggests to me that she is a switch.

Has anyone else dealt with having a keyholder who switches roles? Specifically, someone who can be dominant at times and submissive at others?

I’d really value any answers or insights. Thanks!
