Sex is something that specialists in Autistic Spectrum Disorders never talk about. It's like people with ASDs are never supposed to have sexual relations, which is totally wrong. I've seen one book written about sexuality and Asperger's and not much else. That's why I was thrilled to see that Brazen Careerist's Penelope Trunk has written an article about what it's like to have sex with someone with Aspergers.
The book on Asperger's and sexuality is written by AS expert Tony Attwood and can be found in part on Google Books. If you can get a copy of this, it's quite informative.
On the outer reaches of AS-related sexuality is this article about Aspergers and BDSM (Bondage and Discipline/Dominance and Submission/Sadism and Masochism) and fetish sexuality. It provides an interesting view, especially since fetish sexuality involves so much sensory input. As one person puts it in the opening of the article:
The nerves on my back are so overstimulated from just wearing a T-shirt that a flogging feels like a soft warm summer rain... or what I imagine a soft warm summer rain should feel like, since a soft warm summer rain actually feels like acid drops on my skin.Perhaps this is a topic which needs more exploration as children diagnosed with AS and autism are aging into teenhood.
