What does traditional culture say about the disadvantages of premarital sex and the benefits of postmarital sex?

Premarital sex is not binding. In traditional culture, marriage is a ritual and a responsibility.

Premarital sex is not bound by rituals and responsibilities.

Naturally, there are many disadvantages.

You can break up if you feel bad, you can abandon the person, you can dump the other person.

It has little impact on the man, but it is really a disaster for the woman.

It makes people feel that there is something wrong with the woman's character, that she acts hastily and behaves frivolously.

But it's different after marriage.

A normal relationship, normal behavior, reasonable, legal and beneficial to both parties.
