Well, it depends on the degree of love development. Some people may have physical contact in a month or two, while others may have physical contact in half a year or even a year. This is a privacy issue, and I can't express it clearly here, but most of them are raised by boys. If girls have no clear objection, they may come together, which is nothing. In today's society, it is normal and special for men and women to live together. That's the so-called trial marriage stage, which is what people often say, first try whether it is suitable. If it is suitable for two people to live together, then get married and start a family. If after a period of running-in, I feel that both sides are not suitable, then separate and find true love again.
