cock ring

Hello, just had to tell someone that my 50mm metal cock ring was allowing lots of movement. In fact I could actually remove it by pulling myself out...it was very comfortable but not right at all. Last night I managed to get on a smaller ring, 45mm not much different, and the whole device is tighter.....the cage fits snug, with no movement at all. It does feel uncomfortable if I get any way aroused.....shouldn't be getting that I hear some of you saying. I will persevere with this smaller set up for as long as I can. It feels like the very first time I put on a device....am I getting smaller or just used to wearing my device?
