The Secrets of Underwater Sex in the Bath
"The secret to good underwater sex," writes Suzi Godson in The Times, "is lots and lots of lube." Not water-based lubes, Suzi says, because they wash off, but silicone lubes which are resistant to water and will last and last and last.
Suzi recommends Sliquid Ride SIlicone Lubricant, because it's also vegan-friendly, non-toxic and free of glycerin and parabens.
Another good choice, she says, is Yes Organic oil-based lube which is packed with lovely things that are good for your skin.
