Novices and newbies discussion

(Apologies in advance for my English.) Hi, I need some advice. I’m 21 years old and really keen on trying chastity. However, it hasn’t been very successful yet. I’ve tried the CB-6000S along with a small HolyTrainer3, but neither quite works for me. The issue is that my testicles are quite small because I don’t produce much spermatozoid, so the cage tends to fall off since there’s too much loose scrotum skin. I feel like I need a device supported by my hips rather than hanging from my balls. I know about chastity belts, but they aren’t really in my student budget right now, and I doubt I’d wear one at university. I don’t want to spend more money on another device if I’m not completely sure it will work. So I need your help and experience here. I’m not quite sure what I’m looking for: a chastity cage with hip support? A cheapish chastity belt—not necessarily top-tier, but comfortable and secure—that doesn’t have to be worn 24/7? Or perhaps some kind of hybrid between the two? My budget is around $600 CAD / $458.31 USD. Thanks in advance.
