How can one stop looking at men after overcoming the problem of homosexuality?

Your feeling that homosexuality is a problem is the beginning of the right path, and repentance is the effective cure. Looking at men with suspicion is one of the greatest means of falling into homosexuality. Exaggerating the sinfulness of it and sincere repentance help in avoiding this forbidden gaze, in addition to following the path of righteousness, being keen on the company of good people, and avoiding the company of evil people.
