Here are videos that were developed for 10 – 17 year olds on the autism spectrum regarding puberty & other sexuality topics. They are clear, concrete, and move through the material slowly (this is one of the biggest problems with videos for a general audience- they go too fast!)
My favorite thing about the videos is that the male instructor is an individual with autism.
All of the videos can be found on www.coultervideo.com, a website that sells videos by Dan & Julie Coulter. Dan & Julie are parents of a son with ASD who started creating educational videos on their vacation and now do it full time.
