Introductions discussion

Greetings to all here, I trust you are all securely under lock and key or have your keys tucked away safely. I’ve enjoyed browsing the site over the past week or so and felt it was time to introduce myself from Cardiff in South Wales, UK. A special big hello to everyone local; I hope there are a few of us. I believe I’ve always had an interest in submission but only ever dated vanilla partners before. My current girlfriend is what someone on here described as “vanilla with sprinkles,” which fits her perfectly. About a year ago, while single and seeking amusement, I purchased my first cage and adored it, even though it was too large and bulky to wear for long periods. Shortly after, I bought a Holy Trainer, followed by a metal one from the House of Denial, and having read discussions here, I’ve switched (or perhaps downgraded) to a very petite cage. My main issue is my balls escaping. I’ve seen others discuss this online where men treat popping out as merely an annoyance, but for me it’s agonizing. I’ve endured needles in both scrotum and nipple, yet the ball pain brings tears to my eyes; knowing it’s coming makes it even worse. My testicles sit quite high against my body, so no spacious sac for me unfortunately. I’m unsure what to do next. My partner and I are planning a lengthy period of chastity together, but I don’t want to endure that pain again. Any advice would be much appreciated.
