Lubes

Sexual lubricants fall into three main groups, oil based, water based, and silicon based.

Each has a different feel, advantages and disadvantages.

Water based lubes are generally a safe bet for any situation, safe with condoms, safe with insertables. The downside is that they tend to dry out. And some of them taste nasty. Adding a few drops of water will refresh the lubricity but nothing will help with the taste. Best to start with with a flavoured brand.

Oil based lubes last better but will be absorbed and more will be needed. This is not usually a huge problem, a far more important downside is the effect oil based lubes have on latex condoms. Any oil based product will degrade a latex condom very quickly.

Silicone based lubes last well, they don't seem to be absorbed as quickly as oil based, if at all, and have very high lubricity. They are also safe with latex condoms. The downside of silicone lubes is the effect they have on silicone toys. Keep silicone lube away from silicone toys. Use a condom on the toys, it protects them from the degrading effect of the lube and makes clean up easier, silicon lube is quite persistant and takes some effort to clean off.
