Nowadays, the society is more and more open, and many young people are very open and tolerant, and they don't think such a thing is strange, so they will live together in the university. But I don't think it's good to live together too early now, whether it's a boy or a girl, but especially a girl. If others know about it, the influence will be very bad, so I think girls should respect themselves and don't live with the opposite sex too early. And if we live together too early now, it will make both sides have certain responsibilities, so that both sides can't study hard too early. So I think college cohabitation is a very bad phenomenon, and we should start from ourselves and strictly put an end to it.
Moreover, if college students live together now, they usually keep it from their families and don't want them to know, so they actually feel guilty. I think if they feel guilty, they shouldn't live together, because they may be sorry for your parents and yourself, so we should respect ourselves and don't live with the opposite sex too early. This is a very serious problem.
I think why this happens is actually because of the lack of education in this field in families and schools, which leads to the fact that many people have little education in this field. I think we should teach this knowledge to young people like other countries, inform them of the harm in this respect, and let them look at this problem rationally and not be too emotional. If so, it should be possible to avoid this problem of heterosexual cohabitation in advance.
