While dyspraxia may occur in conjunction with an ASD, dyspraxia itself is not an autism-spectrum disorder and I highly recommend you seek out a specialist in dyspraxia and childhood sexual behavior right away. Individuals with autism may display inappropriate sexual behavior but this isn't a specific characteristic of the disorder but rather typically a delay in learning what is and is not appropriate. In the case of your son, it sounds like you are taking a reasonable approach in making sure he is not alone with other children and looking for a specialist to help. This is obviously a serious issue and one that requires immediate attention.
