Men may enjoy the penetrative role during anal intercourse due to its association with dominance, as a result of it is made more alluring by a feminine companion or society in general insisting that it is forbidden, or because it presents an additional choice for penetration. Stimulation from anal intercourse can additionally be affected by well-liked perception or portrayals of the activity, such as erotica or pornography.
