Chastity and orgasm denial discussion

I’ve experimented with a few ball trap gadgets. Over the years, I’ve used cages of varying lengths and ring diameters ranging from 40 mm to 50 mm. Essentially, there are two results:

• I manage to pull out. I haven’t tested pushing it back in yet, but doing so would likely ruin the experience. (Sizes: 45 mm, 50mm)
• The base ring is tight enough that my scrotum turns dark red even without a cage inserted. It might be intentional, but they don’t look very healthy. Additionally, the penis gets quite rigid with prominent blood vessels and darker coloring. I’m skeptical about whether this is beneficial. Regardless of which ring size you use, erections tend to drag the device down, tugging on the testicles. This isn’t particularly comfortable, nor do my balls seem to enjoy it much. I owned an inexpensive Chinese full belt featuring a compartment for the scrotum, akin to the “My-Steel Untouchable Premium” or spiritually similar to the Latowski model. It was quite pleasant to wear, except the lock stopped accepting the key while I had it on. That’s why I no longer have that particular one. What approach do you all take with ball trap gadgets? Are there physiques simply unsuited for them?
