Not all sex toy materials are made equal. Some are semi-porous or even porous. This means these materials are riddled with tiny little holes which can allow bacteria to live and thrive. It also can transmit disease from person to person.

Non-porous materials have none of these holes and are much safer for long term use or for sharing between partners (with sterilization in-between).

What are your favorite non-porous sex toy materials?

Edit: I'm sorry, I botched the poll. Just post to tell your favorites.
