Hello everyone, I’m from holland. I started a few moths ago with the ch6000. Now I just bought a holytrainer V3. When I get a erection the device is pulled to the front, and later when i’m Flaccid the device is not filled up anymore because it has moved to the front...... I think I need a smaller ring, does someone recognize this problem? No I use the 45mm ring. Thanks for helping me.
