From this article in the Nation:
In Cincinnati, Ohio, a high school sex education teacher carefully places a Jolly Rancher candy on each student’s desk. The 14- and 15-year-old students feel the crinkly plastic wrapping in their hands, wondering when they will get to eat their tantalizing treats.
“Don’t eat the candy!” warned the teacher, although she had just finished placing one on each desk. “You must wait until after class. It will taste much better if you allow yourself to wait.”
Obviously, this woman has never had sex. Because if she had, she would know that the first time you have sex is awkward and weird, a little embarrassing, and not all that great. For some people, it's painful. It's not candy.
She would have been better off giving them something they could practice at. Like, I don't know, musical instruments. I bet if they practiced the kazoo every day for a week, they would find playing the kazoo a lot more fulfilling than when they first began. It might even be less embarrassing.
