Is it permissible to break the oath sworn by the questioner on the Mushaf not to approach his wife's anus again after having done so for the first time?

Sodomy (anal intercourse) is forbidden and considered a grave sin. Repentance from it is accepted if its conditions are met: abstaining from the sin, regretting it, and resolving not to return to it. As for swearing oaths and invoking curses upon oneself, this is a course of action that may cause more harm than good. Therefore, it is advised to strive diligently in achieving repentance and to be wary of the devil's enticements.
