Didn't expect the 18 cm to feel this comfortable, but the silicone has just enough give to it. We tried it both ways and the harness didn't dig in at all.

The adjustable belt actually stayed put no matter how much we moved around, which I didn't expect at this price. The 18 cm size hits a nice middle ground too, not intimidating but definitely enough to feel it.

We were nervous about trying a strap-on for the first time, but the adjustable belt made it feel way less intimidating and it fits both of us comfortably. The 18 cm size is just right for role-play without being over the top.
