A teacher has shared the funniest questions her curious students asked in class after their first sexual education lesson.
The students are believed to be from a US school and many of them just can't seem to wrap their heads around the concept of sex.
The hilarious questions have gone viral after one of the teacher's friends shared them to Twitter.
"My friend is teaching elementary schoolers about sex ed and she typed their questions out," the friend wrote alongside pictures of the questions.
"I am sure my mother never had anything to do with intercoursing … maybe my father?" one student asked.
