Female led relationships discussion

Hello everyone, I don’t seek assistance here very often; I’m mainly around because I love the lifestyle and it’s wonderful to connect with people who share my interests. However, a new problem has appeared. I am a dedicated 24/7 long-term chastity b1tch under my key holder’s control. The current issue is that after her key/had a rough day recently, she found an inner dom and is now thrilled and eager to ball bust me more intensively. We’ve experimented with it gently before, but now she wants to treat my balls like a professional. It frightens me slightly, yet I’m ready to accept the challenge and feel a bit of nervous excitement too. Since this is new for us and I lack real experience, I’m unsure what to anticipate. People often share scary tales about ball busting leading to cancer or ruptures, even losing one ‘up north’ for a day or two, but from my reading on different sites, these seem like old wives’ stories with little medical proof. Of course, damage could occur if she goes overboard, though I trust her not to. If anyone has experience giving or receiving ball busting, please share your thoughts. P.S. Admin, I was looking for the medical suite to post this because I’m certain it used to be here but seems to have vanished. Am I losing my mind, or did it really go? Thanks in advance.
