To do this try to draw an imaginary circle around your waist with your rear end. And then there's thrusting together - there are two ways to do it. As the man pushes his penis deeper into his partner's ass, they can push against you and then pull away from you as you pull away from them. This is the meeting style. In the rhythm style, you both thrust at the same time; you make the exact same rhythm. Obviously this would never work, except that you and your partner don't move at exactly the same time: one of you is "off" slightly, pushing down a little after they pushes down, pulling up a little after, and so on.

There's another important matter that's good to know. And this is about forcing your partner's ass. There are two ways to have anal intercourse as in inter-action, or as a game of force and selfish controlling between suspicious partners. Time and again, it is the good consciousness that matters; feeling warm, trusting, open with your partner. With this attitude, the problem of forced entry will never come up. But it often happens that a tight anus is rammed by a callous or overeager partner, and this is not good. As I've taken time to explain, the anus muscles will be as loose as the person feels. If the anus doesn't relax, intercourse can still happen, as the ass can be entered by sheer force. This is usually painful, and may hurt the ass-person by tearing the rectum.
