Which sex toy material is best for beginners?

Silicone is the easiest all-rounder for most beginners: it is soft, warms quickly, is nonporous and is simple to clean. If you want a low-cost first vibrator, an ABS bullet is also a good nonporous option. Glass and metal are lovely once you know you enjoy firmer pressure. Pair any of them with a water-based lube and a gentle toy cleaner.
