How to deal with colleagues who like to swear? In the workplace, the kind that doesn't offend each other and speaks well?

In that case, you can tell them with a smile that everyone is an adult, and I'll take that as a joke. I think it's nothing to say it over and over again. It's boring to say too much. After all, you are so much older than me, and you always have your own children. If you are so interested in these topics, why not give your children sex education in advance? Or if they joke like this again, you still smile and ask them, is that what you told your children in sex education class? See what they say.
