I ordered the Sliquid H2O about two months ago and love it. I use it on my toys as well as for vaginal intercourse. I have not used it for anal sex, but it may work. If you are concerned, Sliquid has a lubricant made specifically for that called Sliquid Sassy Booty. Occasionally I have some problems getting wet depending on the time of the month, and this helps jump start the process. If you have extreme difficulties getting wet and ready, I cannot tell you what effect it may have for you. In my experience, I've found you only need a small amount, and neither of us feels sticky afterwards. I find that it is the most natural lubricant out there to most closely match my own body's lubricant. One of my friends finds it becomes inactive as it gets closer to an hour after application, and in that case you are to reapply or add water. My favorite part is it has no fragrance or flavor. There is just something weird about artificial flavoring.

I picked the Sliquid brand over the others for the follow reasons:
-DEA free (may react with other ingredients to form a carcinogen)
-Gluten free
-Glycerine free (draws moisture out of skin)
-Glycerol free (draws moisture out of skin)
-Paraben free (may lead to breast cancer, skin cancer, low sperm count)
-PEG free (carcinogenic, may be genotoxic)
-Propylene glycol free (an ingredient in antifreeze you use in your car!)
-Sorbitol free (may cause gastrointestinal problems)
-Sulphate free
-Vegan friendly

On top of that Sliquid H2O is:
-water based and water soluble (safe for toys)
-hypoallergenic for MOST people (I'm sure someone out there could still have a possible reaction)
-non-staining
-fragrance free
-flavor free

The ingredients are as follows:
-Purified water
-Plant cellulose (from cotton)
-Cyamopsis (Guar conditioners)
-Potassium sorbate
-Citric acid

I am still very happy with Sliquid H2O. I also wanted to note that it doesn't leave any sort of residue on clothing. The expiration date on mine is September 2015 (I received it November 2012).

The bottle it is packaged in has a recycling symbol on the bottom. This means the bottle is made from PET or PETE (polyethylene terephthalate). This plastic does not contain BPA. According to the rare studies there are on the subject, it poses low risk of leaching breakdown products. Until more research can be done, please keep it stored in a cool place because storing it in high temperatures could cause leaching to occur (this goes for any plastic). Also, please note that the longer something sits in a container, the higher chance it has of chemicals leaching into it. So don't always be a penny pincher with your lube!
