Chastity and orgasm denial discussion

Hi everyone, I’d appreciate some guidance on urethra devices from those who have experience. I currently own one with a tapered stainless steel tube, which helps make insertion smoother. Still, it feels uncomfortable after about eight hours of wear. How do other styles stack up? Several designs feature a bulbous tip instead. Does that shape help or hinder during both insertion and long-term wear? Additionally, there are silicon tubes capped with stainless steel tips. I’m not sure how those stay in place so well—I’d love to hear from anyone who has tried them.
