Quick answer

Choose the Severin Soft if you're gradually working up to larger sizes with a long, tiered neck. Choose the Fido if you want an advanced toy with a pronounced middle knot and ribbed shaft for intense internal stimulation.

Design and sensation difference

The Severin Soft uses a two-tiered shape with a long neck, letting you progress through sizes as your muscles relax. The Fido features a middle knot that releases pressure when inserted or removed, plus ribbing on the upper shaft to stimulate the inner anal muscle band.

Trade-offs at a glance

  • Experience level: Severin Soft suits intermediate users who want to gradually increase size. Fido is for advanced users who already know their limits and want a knot sensation.
  • Sensation type: Severin offers a smooth, gradual stretch. Fido provides a distinct pop-and-release feeling from the knot plus inner ribbing stimulation. If you prefer constant pressure, choose Severin. If you want a pronounced pop, choose Fido.
  • Size progression: Severin comes in three sizes to help you advance safely. Fido is a single size with a knot that demands more experience to insert and remove comfortably. Beginners should start with Severin's smallest size, not Fido.
