This is another material that is becoming more popular in recent years. Glass offers the smoothest surface out of any material used, but that is only one benefit. They can be created in all shapes and colors, and because many are hand blown, they are more like a piece of art than a dildo. They tend to be more expensive due to this, and they can last a lifetime.
However, if you are in the market for a pink suction cup dildo, may I recommend this one? It's got a slight curve to hit all your sweet spots and the suction cup on the bottom means you can attach it onto your shower walls and ride it while stimulating your clit/deep conditioning your hair. Plus if the idea of coming home and seeing this beautiful pink dildo attached to your shower walls doesn't make you smile, then TBH what will?
This silicone anal toy from B-Vibe is small enough for beginners, so it will feel good but won't hurt. If your partner has a vagina, have her wear it during vaginal sex for extra intensity, or to warm up for anal sex. If you have a prostate, enjoy the vibrations (oh yes, it vibrates) during sex, or a nice old-fashioned hand job to take your orgasm to the next level. (Side note: Using a water-based lube is recommended as silicone lube can break down silicone toys.) Sex Tpys
