Dildos

Choosing a dildo comes down to three things: material, shape, and whether you want it to stay where you put it.
Dual-density silicone — a firmer core under a softer outer layer — is what most people mean when they say something feels realistic. A flared base makes a piece harness-compatible and, for anal use, non-negotiable.
Length is the specification people overestimate. Girth and curve change the experience considerably more.
