This never happened to me. I do recall watching a movie about reproduction. It was pretty intense. In fact, I even had to leave the classroom! I was the only kid that did it. Boy, did I look stupid.
It was unsettling seeing pictures of STDs. Wow, those people were brave to allow their diseased genitals to be photographed. I was always a good student. I never had to do a project on STDs. Of course smoking's bad.
