@cmsmith10- I think that what your school is doing is a great idea. I am not a counselor but I work as a teaching assistant and I end up talking to a lot of the kids about personal things such as infectious diseases.
We had a guest speaker to come to our school a few months ago. It also was mandatory attendance. She was 20 years old and she had genital herpes infection. She has been going to different schools telling her story and motivating others to practice abstinence or to use protection. She said that she contracted herpes during one sexual encounter. Only one.
