Burg's question is "can you have sex without validation?"
Of course you can have sex without validation. I thought his question is whether sex with validation is better than sex without validation and if so, why?
But then what definition of validation is he using? If you assume that he is talking about sex that is not "forced", then by definition isn't any sex "validation." By having sex with Raven haven't I validated that I want to have sex with him?
However I think Burg was referring to the fact that it seems Cemar has expanded the "validation" to mean that he needs sex from his wife to prove that he is worthwhile and desirable as a man. So he needs his wife to pursue him in order to feel good about himself. That's why "merely" having sex is not good enough for him because he seems to need a deeper validation than her participation.
But what is happiness except the simple harmony between a man and the life he leads? ~Albert Camus
