A douche is the flooding of any body cavity by a liquid, in most cases water, although a mild astringent, such as vinegar, may be added to enhance the cleansing effect. Disposable plastic bottles, designed specifically for this and known as douche bags, are readily available at chemists or other drug stores, and can help to keep the vagina clean and healthy. Those wishing to indulge in anal sex may also be wise to douche the rectal cavity, depending on how much respect they harbour for their partner, and how much they value hygiene.
Some women, however, labour under the misimpression that douching the vagina after sex can somehow help to avoid pregnancy. Douching is rated as the least effective form of birth control, even falling behind the rhythm method. It is well known that sperm can enter the cervix as little as one minute after the release of precum, and it is for this reason that those concerned with birth control would be best advised to look elsewhere.
As it happens, and despite what you might have read, douching is extremely popular with the gay community, and with good reason. Although the same applies to heterosexual anal sex, the gay community is more keyed into using the anus for pleasure, and thus more accepting of the associated pitfalls. It happens. No matter how thorough the anal douche, eventually, over a lifetime of anal sex, one is sure to encounter the smearings of what can only be described as shit. An anal douche will reduce the risk greatly, but there are no guarantees.
With regards to anal douching, there is no need to shrink back in fear. Any moderately sized bulb contains quite enough water - it's not even necessary to squirt it all in. The whole thing is simple, if blatant. Defecate, insert the nozzle, squeeze in, and remove the douche. Expel the water, noting the expulsion of other, more solid bodies alongside. And this is it... continue until clean.
How do you know you're clean? Squeeze... it's simple and natural. Wait until you're almost completely expelled and press a pad of toilet paper against your anus to check what's coming out. Is it clean water? Have fun! If not, rinse and repeat. It's that easy. Once you're expelling clean water you're okay. Don't fill yourself up too much, don't expect miracles. You like anal sex? Then once in a while you're bound to encounter something brown. Live with it. Take a towel to bed, always use a condom. Be happy.
