Is it normal to tell dirty jokes to your boyfriend?

Actually, this is quite normal. What is normal for men is abnormal for women. Girls must respect themselves, don't be so frivolous, and learn to exercise restraint.

If your boyfriend keeps talking about this topic, you can change the topic yourself, and don't always chat casually with the other person, otherwise the other person will think that you are particularly casual and will make it worse. In daily life, you can talk with your boyfriend about some topics of interest to you, or talk about some hobbies, which can sublimate the feelings of two people.
