For me, marriage is both an outdated and terrifying prospect. The thought of being with one woman for the rest of my life, sexually, is off-putting. So instead of doing what many others do - cheat, get caught, divorce, repeat - I just choose not to marry. Unless I find someone of a similar mind-set.
Dating sites are filled to the brim with women/men who want a "discreet" relationship. Instead of being open about our needs and communicating and accepting those needs, we choose to hide/vilify those who are brave enough to do. So as a society we keep up this fake appearance of "proper" when increasingly more and more are cheating, getting divorced, being miserable...why? Why is this necessary? I don't get it.
Sorry for ranting. It's just what you said struck a chord with me.
