Girlfriend is 2 1 year old, but she knows nothing about men and women. How can I guide her correctly (I don't want to take advantage of people's danger)?

This is normal. Before I was 23, I was introverted. I dare not look the boy in the eye and speak. I've never shaken hands with a boy. I don't read pornographic books. If the projection is yellow, I will leave.

The first time I had zero-distance contact with him, I was particularly scared when I saw that new thing, and I shouted in my heart: Oh, my God! ~ what's going on! I can't believe my eyes are at a loss ~

Let her read some books about sexual health in advance. Then, the two watched porn together and immediately entered a state of ignorance.
