There are three types of lubricant: oil, water-based and silicone.

Oil based lubricant is a good choice for really tight holes as it is the most powerful lubricant. However, it is also the hardest to clean off. It is not recommended for anal sex as it is hard to remove.

Water-based lubricant is a good choice for regular sex partners as it is quite a light and very clean lubricant. It does have the tenancy to dry out though, which can potentially cause rips in condoms.

Silicone lubricant is a bit of an in-between. it is more powerful than water-based lubes and easier to clean off than oil based lubes. It is a good choice for all occasions and is anal sex safe.
