Revenge

Sometimes people want to revenge and to hurt people who offended them. In such case they use sex and sexual preferences to harm people. For example, if your boyfriend/girlfriend cheated you with your best friend. In such case the only thing left is to revenge, to abase him in sex and in his entire life.
There are so many reasons why people start to revenge and why they start to use sex as the way to revenge. Of course it is unacceptable from moral point of view. But when a person is offended he/she doesn't control his/her feeling until he/she finally revenged.
Sometimes people use sex to hurt people they love. For example I had a friend that had sex with her ex because her present boyfriend cheated her. In such way she revenged him and maid him suffer too. But of course it didn't help. And the only person who suffered was she.
Sex is the phenomenon created for getting pleasure and love but it is not the instrument to revenge people. And if you are in love with someone, revenge is not the best thing to solve the problem and especially through sex as sex is individual and intimate that exists between two people.
Sex must bring pleasure and not harm people.
