Of all sexual acts, anal sex is the most misunderstood. Despite the fact that one out of every four women has engaged in anal sex, the practice remains taboo. Many women are reluctant to experiment with anal sex because of the many myths and misconceptions that surround the practice.

But once you learn the right techniques, it's easy to see why anal sex can be so enjoyable. The anus contains a vast supply of nerves, and is one of our most sensitive erogenous zones. Stroking, massaging, and otherwise stimulating the anus can be intensely pleasurable. In fact, some women are able to orgasm from anal stimulation alone. Here you'll find answers to the most common concerns about anal pleasures:

1. The anus is dirty.
Early in our childhood, we are taught that the anus is dirty and should not be touched. Thorough hand washing after accidentally touching this area is stressed. You may also have heard similar sentiments voiced about your vulva and vagina, but of course stimulation of these body parts can certainly provide a multitude of pleasurable sensations.

With routine daily hygiene, the anus is as clean as other parts of your body. It does contain its own natural bacteria, though, and to avoid infections, you must never move anything from your anus to your vagina.
