Novices and newbies discussion

Hello everyone,

I’m fairly new here and have a few questions regarding chastity. I used a string to measure my diameter, which comes out to approximately 65mm when flaccid. (According to the HolyTrainer page, this size typically calls for a 55mm base ring).

My collection includes an inexpensive Chinese version of the CB6000 with interchangeable rings (sizes: 49mm, 46mm, 43mm, 38mm, and 35mm), as well as another stainless steel device from China that uses a 45mm ring.

I’ve discovered that rings between 40-45mm fit best; they stay in place while flaccid without cutting off blood flow or causing pain. However, my issue arises when I get an erection: all the smaller rings become too tight for me. This restricts circulation (especially with the plastic device) and stretches my testicles because the penis pushes forward against them, sometimes turning a slightly darker shade. On the other hand, if I use the 49mm ring while flaccid, it is quite loose—it slips down past the root of the penis rather than sitting firmly there.

I really want to avoid slipping because it would be too easy for my penis to pop out of the cage when soft.

So, what size do you recommend? Also, is it normal for testicles to turn blue while erect?

I plan on wearing one 24/7.

Thanks in advance.:)
