Why emphasise on monogamy?

[Fidel_Castronaut]

Monogamy helps to create more stable social relationships, is connected with less violent crime, is a more obvious source of financial and emotional support for children and helps people break out of the selfishness of seeking sex for the purpose of hedonistic indulgence (which treats people as a means to an end).

Sex is actually just two consenting people (or maybe more, who knows?) who want to use their sexual organs for some gratification with others who are of the same mind. 

Maybe some people *want* to be a means for an end, or maybe some people just have a lust for one another and want to fuck. Nothing wrong with that at all, and thinking there is, leaves you about a century behind the rest of us. 

If I want to indulge in some hedonism (oh, and I do, frequently), then I will. ^_^
