Lying is something that is frowned upon by the society, it's even illegal to lie in some situations and you can get sent to jail for it.
I don't think people really realize how dangerous the concept of deception is.
Deceptive to who? The couple decides to do thos to each other not to society. I don't see how it is considered harmful to society if the couple decides to have an alternative lifestyle. If society doesn't believe in it, then don't do it. Everyone is different. I guess in my view, whatever goes on in other people's bedroom is not my business.
