This question is an important one. Actually in our society, male sexuality is taken for granted. We think that male sexual response will happen no matter what. However, that is not the case. If you know Sexual response cycle, you will know that the first phase is the desire phase. If any problem occurs in that l phase then the arousal (which is the next phase), will not be adequate. Now arousal phase may be affected by n number of factors including the presentation of any Psychological disorders like depression. Please be informed that the most common cause of erectile dysfunction around the world is Psychological condition. However, biological issues are also important including age, presence of long standing illnesses, trauma, endocrinological factors etc. The best way would thus be to consult a sexologist.
