You should only look at Prophet's life to know this truth.At a time when the whole world was freeely practising unlimited polygamy,Muhammed lived with a single wife Khadeja throughout his prime life (up util 50).All his marriages (including with Ayesha) was after this age. He prayed most of part of his night until his legs sore,went without food for many days despite being the head of state and commanding enormous influence,not to mention his frequent fasting - do sensous men lead a life like this?
