We discussed pleasure, various things that please them, and their most pleasurable moments. Some of them could define pleasure, while others talked about its instances. I realised pleasure is such a wonderful emotion; you can just feel it! As Wikipedia describes it (http://en.wikipedia.org/wiki/ Pleasure) pleasure is most commonly conceptualised as a positive experience, happiness, entertainment, enjoyment, ecstasy, and euphoria. However, is a difficult concept to define as the experience of pleasure differs from individual to individual. People commonly experience this phenomenon through eating, exercise, sexuality, music, usage of drugs, writing, accomplishment, recognition, service, indeed through any imaginable activity, even receiving pain (masochism) and inflicting pain (sadism). It also refers to enjoyment related to certain physical, sensual, emotional, or mental experiences. Jeremy Bentham, an ethical hedonist, believed the moral rightness or wrongness of an action to be a function of the amount of pleasure or pain that it produced.
