Introductions discussion

I’ve been hearing that both girth and diameter play a significant part, though perhaps not as crucially as the base ring itself. My current girth measures 4 inches, with my flaccid penis at about 32 mm across. Since I’m primarily a grower, this can expand to 36 mm in certain conditions or shrink down to around 30 mm during others.

The real question is: I’ve located two solid devices that offer an acceptable cage length of 55mm for another attempt at chastity with patience. Both seem good and are similarly priced. This first option features a 30mm diameter paired with a standard circular ring (clamp style w/padlock):

The second one offers a 33mm diameter along with a shaped ring (w/micro key lock):

I suspect the images might be misleading since the descriptions mention a 55mm cage twice. What do you think works best for someone with a 4-inch girth and roughly 32 mm diameter? Is being 2 mm shorter problematic (sometimes creating a tight squeeze upon entry) or is 1 mm larger worse (sliding in easily when flaccid)?

As I often mention, various members have pushed different options my way: A. The 33mm size serves as a good compromise if the penis’s resting diameter fluctuates around that mark. B. The 33mm appears too tight because the pressure causes it to slide down. C. The 33mm feels excessively large, causing slippage when shriveling down to 30 mm in diameter. • And vice-versa applies to cages with a 30mm dimension.

Regardless of other factors, the cage’s girth must remain smaller than that of your flaccid penis. That covers girth…but what about diameter? Overall, I am content picking either one but would appreciate more feedback on this topic here in this thread.

I believe we receive such varied recommendations simply because every individual's anatomy differs. Because my flaccid penis is relatively large, I prefer a smaller cage to compress it so it remains less visible under clothing. However, there are limits to this approach. One key factor in determining cage diameter is your personal tendency toward edema (fluid retention). If you develop edema easily, you likely need a looser fit; that applies to me. While I prefer a snug tightness, that often triggers swelling for me, so I must select a size that avoids excessive pinching. For my case, it varies somewhat. I believe edema tends to form mainly in areas where the skin can bulge out and trap fluid. A diameter that closely matches my flaccid state works well for me naturally. Of course, sometimes when my penis is smaller than usual, the cage looks oversized, while other times it appears larger due to fullness. But since I don't suffer from edema issues with this size, it proves effective. You will encounter similar conflicting advice regarding length as well. Again, context matters depending on both the specific device and your own anatomy. Some men are very satisfied in much shorter cages, while others desire devices that precisely match their flaccid length. I perceive a connection between length and diameter. My experience with this is limited, so it remains largely theoretical. My theory suggests that if you choose a short cage that compresses the penis's length, you require a larger diameter to provide adequate room for tissue expansion. Without sufficient width, the device gets pushed down further along the shaft. One certainty from my own experience: when an erection forces a short cage downward, it drags the testicles with it and pulls painfully on the scrotum—a sensation I can certainly avoid. In practice, what prevents this sliding and tugging is the cage gripping firmly around the root of the penis. This happens if the shaft swells upon erection onset and presses against the device before gravity or movement pushes it down the shaft. That was my experience with the CMC contender model. It matched my flaccid length perfectly and contained erections effectively, proving quite comfortable. In contrast, the Holly Trainer felt too short and narrow; it failed to contain my erection entirely, pulling on the testicles painfully. However, perhaps the Contender worked for me because its shaft was noticeably curved, which played a major role in containment. Additionally, I am pierced and have worn PA tube devices exclusively over the past year. Please feel free to disregard these suggestions if they do not align with your personal experience. The good news is that cages are quite affordable nowadays. You spent only $78 total, which isn't excessive. Moreover, it wasn't wasted money since you managed to test four different models and identify what didn't work for you.
