Difficulties with wearing a device? discussion

I recently picked up a chastity cage equipped with a catheter for myself. I’m really looking forward to using it, but have hit a couple of snags… The flow isn’t quite normal; instead of a steady stream, there’s just a thin dribble. This creates a fluttering sensation in my urethra as urine passes around the tip, which soon turns into bleeding because the tissue is so sensitive. My first query: should I trim off the stainless steel tip at a 30° angle? Also, I can manage wearing this chastity cage for almost 23 hours without much trouble. However, morning erections are incredibly painful! What’s the best way to stop that from happening?
