Hello, I am thinking of buying a rigid chastity model 5. I am larger then average but not pornstar huge. 1) *Base ring...Is it better to have it snug, or as wide as possible for long term wear? I feel like if you can sneak balls through ring, You can pull out? Hard to know whats comfortable vs security? a 2) I get the basics of measuring cage length, but if it is a little snug, or a little bigger is this an issue? No prince Albert. like when you try and grow...the tip of the cage? I had a jail bird, i think, that had a sharp weld at the tip, when I'd get fully erect it would sometimes scratch me... got rid of it. 3) interior diameter: The site recommends using the girth erect...But I am curved up, while cage is curved down and the cage is recommended to be shorter, so I can't imagine ever getting fully hard in cage? 4) interior diameter : I have a bon4L...which was skin tight (Diameter) on my flaccid penis. Didn't allow any air in or out..which caused chaffing and moisture to always be there... I am thinking of a getting it big enough to have air with flaccid, but just a smidge under my full erection. To much space can allow pull out? I am eager to have a quality device. I also considered the Pet Trap from mature metal. any other custom devices I should look at?
