I’ve been using 50mm rings which although comfortable seem to slide down my body, more so when I have an attempted erection. Am now trying a curved 45mm base ring which seems to hold close to the body a lot better though it does feel quite snug. Like to keep the base ring on when I’m allowed to be unlocked to play but then it does feel quite tight on the 45mm. Does this look like a good fit?
As long as you can get a finger under it, and your balls are not cold or discoloured then it should be fine.
