9.2cm aluminum jewel plug beginner — Diamond Bum S

The Diamond Bum S from ToyJoy: the gateway to metal plugs. 3 cm at its widest, 7 cm insertable, mirror-polished aluminum with a faux diamond in the base. This is the perfect size to discover how metal compares to silicone, without getting overwhelmed by the caliber.

Practical for testing metal plugs for the first time

If you're used to a 3 cm silicone plug, the aluminum S will give you a different experience at the same size. The complete rigidity changes insertion—metal doesn't bend or compress. The polished surface glides remarkably well with a bit of lube. And the weight, even at this size, is noticeable from the first wear.

Cold/hot thermal play

Aluminum retains and conducts temperature. A few minutes in the refrigerator and the initial contact is cool—10 minutes in a bowl of hot water and it's the opposite. Cold/hot thermal play is one of the main appeals of metal, and the S size is the right place to experiment with it. Non-porous, sterilizable, compatible with all lubes.

A size to approach methodically

This plug benefits from being approached slowly, with enough lubricant and true listening to your body. The size, texture, or curvature aren't meant for you to take it all at once: they mainly provide benchmarks for progressing in stages. You maintain control, adjust the angle, and let the sensation build without forcing it.
