Can the vibes be used anally?

A vibrator with a base or a sturdy cord can be used anally. If it's a corded egg vibe then you would use it anally with a condom over it (see above). If your vibrator is made of silicone and has a base on it then you can use it as is (with lube of course), otherwise, use it with a condom to keep it thouroghly clean.
