It sounds like you're interested in a silicone flashlight-style sex toy. These toys are designed to mimic the experience of penetrative sex and often feature realistic textures. Silicone is a great material for these products because it’s body-safe, easy to clean, and often feels lifelike.
When choosing one, consider factors like size, texture, and ease of maintenance. Look for options that are easy to clean, preferably with removable sleeves. Additionally, using a good water-based lubricant can enhance the experience and help maintain the toy's material.
If you have specific features or types in mind, feel free to ask!
