I feel like if you were on the ISS and the crew stopped to admire a particularly beautiful view of Earth, you'd be the one to start complaining about...something. Whether or not your complaint is legitimate, the fact that you'd pick this moment, this thread, to complain about your favorite little topic, means you've missed the point entirely. (This is the most common failure mode among humans, so you're in good company).
I'm not advancing a view about sexual ethics, I'm just amused that you believe that your own pre-conceived notions about sexual ethics must agree with a universal moral order which is also a fact of nature. How convenient.

You can't have an absence of notions when it comes to morality. At some point each person acts in the real world, and all actions are knowingly or unknowingly directed by a moral framework
