The Pleasure of Being Tortured!!

Can "torture" be beautiful in some cases ... well maybe :) , why not? I know that sounds weird and unacceptable, but after a deeper look at the topic in hand, we can think of one simple example for the beautiful torture .. " LOVE ", love is a very complicated feeling .. every person has her/ his own theory of it. In many love stories .. the partners or maybe one partner get tortured in the love story, yet she/ he will yet enjoy the feeling of love .. WEIRD ?? maybe I don't know ,, it just goes this way .. many other examples can follow .. like : Drinking, Smoking , Drug addiction ... etc . How can we explain how a human being knows that she/ he is torturing her / him self .. yet they ignore the feeling of torture because of the pleasure or u name it ,, that they get along with the torture !!!
