Which chastity gadget suits me best?

Hello,

I’m in the market for a chastity cage and could use some advice on which one to choose.

Online, I’ve come across varying opinions regarding length: some argue smaller is superior, while others disagree. The measurement methods also vary—some take readings at the top, others at the base of the penis—and instructions differ on whether to subtract 1/4 or 1/2 inch…

Here are my stats: Length from bottom (scrotum to tip): ~6cm / approx 2 9/6 inches. Length from top: ~9cm / approx 3 35/64 inches. Diameter: 3.82 cm / approx 1 1/2 inch.

I’m uncircumcised and a significant grower, with about 3-4 cm (approx 1 3/8 inch) of foreskin.

Which device do you suggest for my situation?
