Anal sex can be a perfectly safe activity as long as you take the necessary precautions. You should remember that your anus and rectum do not have their own natural lubrication nor the kind of elasticity the mouth and vagina enjoy. That is why anal sex must be practiced with care. Liberal amounts of lubrication are necessary because the rectal wall can be quite sticky and is subject to tearing and lesions if not kept lubricated. In addition, the anus and rectum are narrow, so lubrication is needed to press inside smoothly.
Condoms are another necessity.
Enemas, douches and other cleaners will not be able to get all the germs and bacteria out of the rectum. Not only is anal sex facilitate the transmission of STDs better than any other form of sex, it can also cause urinary tract infections and other bacterial diseases. Latex protection is essential, and can offer additional slickness. Finally, use your common sense. The rectal wall curves and is thin so long, hard objects can tear your insides.
