Introductions discussion

Hi all! I’m ‘officially’ stepping into a genuine new realm for me. I stumbled upon this site while looking up MCD information on Google.. A bit later, I chose to create an account here since I don’t just want to read stories but also share my own. I am a 24-year-old woman who turns out to be more dominant than I initially realized. My previous relationship showed me that my inner mistress had been set free. I truly liked taking charge and he seemed to enjoy handing over all that control to me. Our partnership has finished, yet here I stand. All thanks to him.. He admitted his sexual desires were ‘not as simple,’ which is partly why we parted ways. Back then, he lacked the bravery to reveal his ‘secret’ to me.. After months, nearly a year of hardly talking at all, he finally gathered enough courage to let me know and showed me into the world of chastity. He wants me to hold the key for him, not just because I can manage him. But also because the connection we share—physical, emotional & sexual—is still alive. We both sense it; we both understand it. He is my vulnerability and I am (without doubt) his.. How should I go about this? Will it succeed? I realize it feels odd since he is my ex.. But I know there are lingering feelings between us. And, honestly, if this is his major dream, I want to be the one who shares & lives through it with him. (I don’t believe he would tell another girl, but still.. Any tips for me? For both of us? Thanks & see you all shortly.
