I know vaginal douches should be avoided at all costs, but if I'm considering anal sex, should I invest in an anal douche? I've seen a couple on (trustworthy) sex toy websites under the "sexual health" section, and they seem to be considered a good idea by users. But are they safe to use? And, er...how do you use them?! I'm pretty self-conscious, so I want to be assured everything's clean. And finally, should I invest in a specialised anal lubricant, or stick to my usual? Thanks so much.
