That is no way to build a true loving relationship. Communication is a vital part of any relationship. There is no sharing. The sign of a mature relationship is not one that is marked by a physical consummation. Rather, it is the one that is marked by a commitment and full sharing communication between the partners.
Animals can have sex.
There is nothing unique or special in two creatures merely engaging in a physical union. The wonder of a true godly relationship is found in the like-minded fellowship of a man and a woman who share all with each other, growing together as if they were one body. With that as the core of the relationship, such as marriage should be, the physical union that can grow from honest communication is indeed something beautiful and wonderful.
