S, M and L are not standardised across brands. Compare actual measurements and how the shape reaches its maximum diameter.
Maximum diameter
The widest point of the insertable section and the main comparison figure.
Insertable and overall length
The handle, ring and base count toward overall length but remain outside.
Taper, steps or beads
A taper widens gradually, a stepped plug creates distinct transitions and beads repeat diameter changes.
Neck and base
A narrow neck aids retention while a wide base or ring provides control.
How to compare two models
List diameter, insertable length, profile, material and flexibility. Do not rely on photos alone.
Quick pre-purchase checklist
- Measurements are stated.
- Insertable section is clear.
- Base is wider than the neck.
- Shape matches the scenario.
- Flexibility is confirmed.
