Female led relationships discussion

I’m thrilled to share that a friend has chosen to become my Mistress. She already knows her way around BDSM with both men and women, but this is new territory for her. I’ve been curious about chastity for ages and recently picked up a Holy Trainer 2 to start experimenting. Now she’s taken charge of my device—which suits me fine—but she isn’t quite up to speed on the specifics (especially regarding releases and ruined orgasms). Does anyone know good websites where she can learn more? Or perhaps any other tips or ideas would be welcome. Thanks for your help! sissy Jess
