Introductions discussion

To introduce myself, I’ve been captivated by forced male chastity since I first found it. I’m a straight guy with a supportive partner. While I’ve experimented with different devices, none have quite worked for me yet. To be fair, most of what I’ve bought are Chinese imitations so far. The key issue is that I seem to react poorly to metal. Right now, I’m testing out an imitation Holy Trainer model. If I invest in a genuine device, I expect some of my current headaches will disappear. Does anyone have any tips? The biggest hurdle for me is my job as a truck driver; the devices tend to restrict blood flow.
