and what is LUST: . 1. intense sexual desire or appetite.
2. uncontrolled or illicit sexual desire or appetite;
lecherousness.

So the question is which is which. Finding an answer to this is quite difficult but truth be told you as an individual are able to distinguish what each term means to you and how you apply it in your lif.
This may seem as a cliche but it is true when they say "the key lies with the beholder".
I am the only one who can decide what is best for me and people' may have their opinions but I must decide what is good for SAmu and not the next person's well being as I lie with the conciousness and regrets at the end of the day.
It is true that we learn from our mistakes but and keep your head up high and try again until im happy.
