Casual sex is good, or is it?

[Husar]

If you love someone then it follows that you want to make them happy. If what makes them happy is sleeping around behind your back, then you can't really complain.

Or would you all just like to admit that love is completely self-serving?

(Just something I've been thinking about and thought I'd post it...)

Now if we turn that around then your spouse would want to make you happy as well but her/his actions of sleeping around will make you very sad instead, if the person is not very self-serving her/himself then, why would she/he sleep around?
