Wore it around the testicles instead of just the base and the fit stayed comfortable the whole time. The transparent material is soft enough that it didn't pinch, and I could definitely tell the difference in how long I lasted.

Didn't expect the reversible design to make such a difference, but flipping it around the testicles instead of just the base gave a much firmer feel. The clear material is soft enough that it doesn't dig in during longer sessions.

Wore it around the base and the fit stayed put through the whole thing, no slipping. The clear material is a nice touch since you can barely tell it's there.
