潤滑劑
潤滑劑有多種劑型可供選用。有兩個理由可以說明潤滑液應該為水溶劑型：1.它們沒有刺激性，並容易清洗；2.
不像脂溶劑型潤滑液，水溶劑型潤滑液不損壞可能被用到的安全套。 |

有一些女性在肛交中會得到極大的快樂。不過，不像陰道那樣，肛門並不分泌自然的潤滑液，所以利用一些人工水溶劑型潤滑液是明智的。這種潤滑劑最好用於肛門本身。這也為輕柔地按摩肛門括約肌甚或插入手指提供機會。在這種潤滑準備之後，就能夠插入陰莖了。插入本身應該非常緩慢，而一旦進入肛門，有一陣子不應該抽動陰莖，直到肛門括約肌完全放鬆為止。然後，性伴的一方或雙方就可以開始小心地聳動骨盆。
不習慣肛交的女子起初可能感到陰莖插入肛門不怎麼舒服甚或疼痛。不過，在數次輕柔的嘗試之後，即使她本人沒有達到性高潮，也可能會開始喜歡上肛交。當然，她的性伴在肛交期間可以給她手交，如果她確實有了一次或數次性高潮，她因此而發生的肛門括約肌的收縮會給陰莖施加額外的刺激。 |

Lubricants are available in various forms. They should be water-soluble for two reasons: 1.They do not irritate and are easy to wash off, 2. Unlike fat-based lubricants, they do not destroy any condoms that may be used.

There are women who find great pleasure in anal intercourse. However, unlike the vagina,
the anus does not provide its own natural lubrication, and therefore the use of some artificial, water-soluble lubricant is advisable. The lubricant is best applied to the anus itself. This also offers the opportunity for a gentle massage of the anal sphincter or even the insertion of a finger. After this preparation, the penis can be inserted. The insertion itself should be very slow, and, once inside, the penis should not be moved for a while until the anal sphincter is completely relaxed. Then one or both partners can begin some cautious pelvic thrusting.
A woman who is not used to it may, at first, find the insertion of the penis into her anus unpleasant or even painful. However, after several gentle attempts, she may begin to enjoy it even if she does not reach orgasm herself. Her partner can, of course, masturbate her during anal intercourse, and if she does have one or several orgasms, the resulting contractions of her anal sphincter will provide an additional stimulation for the penis. |
