In the crushes unit of Human Sexuality 101 for middle school, we used this video on handling a crush.  We were talking about this during The Birds and the Bees workshop in Champaign today and it reminded me that I should probably highlight this resource on its own.

The How to be in Middle School series covers topics such as how to invite someone to a dance, how to go to a dance, first kiss, handling kissing games, and many more topics (including less relationshipy videos like how to clean your room quickly).  The videos present clear rules and how to guides.  We planned an activity around the rules in our group.
