In The Birds and the Bees workshop we talk a little bit about how we start teaching folks about sexuality from birth. We mostly teach sexuality through how we socialize and interact with infants. SEICUS has a set of guidelines for being more intentional about promoting healthy sexual development in 0-5 year olds. For me, some of the developmental messages and core concepts where exactly where some of the guys I’ve worked with were at, even if they were much older. I especially like the discussions about sexual abuse prevention (pages 56-57), masturbation (45-46), and sexual curiosity (47-49). I also think you could get some great ideas for teaching about gender roles (59-61) that you could do outside of what may be considered a sex ed class. For each of the 19 topics they discuss they include a discussion section, key messages, additional messages for older preschool children, and how adults can help.
