Although such a marriage is unattractive, it continues. So these factors can only be the conditions in marriage, and they are still limited conditions. They can only measure whether the marriage is happy, but can't decide whether the marriage is maintained or continued. Therefore, these are not the bottom line and principles. It is also said that the most important thing in marriage is sex. There is no denying that sex has a great relationship with the harmony of marriage, because only harmonious sex can shorten and narrow the emotional distance between two people to the greatest extent, so that both sides can communicate and communicate to the greatest extent. In order to fully understand each other's physical and psychological aspects. Sexual disharmony or asexual marriage is very dangerous. In the long run, people who are dissatisfied or depressed are likely to cheat because of some accidental temptation, and even take the initiative to come to the door, thus triggering conflicts and opposition. The result is naturally the dissolution of marriage. Therefore, harmonious sex is an indispensable key factor in a harmonious marriage. On the contrary, it is bound to destroy the harmony of marriage and become a dangerous fuse leading to derailment. But is performance the bottom line and principle of marriage? I don't think it is necessary, because even sexual disharmony or asexual love will not lead to the dissolution of marriage soon. It will be a long process from negotiation to psychological struggle, to disloyalty, and then to conflict resolution.
