Answer :

n the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
In this era of immoralities and temptations, it is indeed a challenge on the chastity of a married person to stay away from his wife. The question of the duration of separation from the wife depends on both the husband and wife. They may remain separated due to work related issues, etc. as long as they can maintain their chastity. 
The issue is not only about how long the husband can maintain his chastity; it is about the wife’s chastity as well. If both or one of them is unable to maintain their chastity during the absence of the other, then it is wajib for them to live together to maintain their chastity. 
Anal sex is an abhorrent act. It is haraam and a major sin. The Prophet صلى الله عليه وسلم said:
لَا يَنْظُرُ اللهُ إِلَى رَجُلٍ يَأْتِيْ امْرَأَتَهُ فِيْ دُبُرِهَا
“Allah will not look (with mercy) at the one that enters his wife through the back”
