I know most toys out there are not suited for silicone based lubricants. With that being said, silicone lubricant is what I prefer.
This lube is a little pricey, but a little does go a really long way here. I like to use this lube for anal play and penetration, though it works just fine with my pussy as well! The lube is very slippery, and too much can tend to dull sensations. Be sure to experiment to find what works best. I use a dime size circle to start and then add in small droplet increments when I need a little extra help.

This lube pours so quickly out of the tube that you don't even need to squeeze it. Use with caution! The lube does feel a little greasy, but it's not enough to make me notice in the middle of all of the action going on. The lube isn't very thick and doesn't create any additional drag on its own.

This lube has no taste or smell to it. I do not use this product orally, though I imagine it would taste pretty bad.

This lube lasts the entire duration of play. Very rarely do I (if ever) need to reapply. The lube can be wiped off. It will stain your sheets, towels, and any other fabric. After wiping it off, you will probably still feel a little greasy. I would highly recommend a shower after using this product.

The lube comes in a black plastic container. It's not discreet and could potentially leak all over your clothes if you travel with it. I would pack it in a few plastic baggies to be safe.
