There's no easy solution. If you don't want to do it, you'll have to communicate that to others and be assertive about it, which likely isn't something you're good at with the asperger's. One way to make it a bit easier is to get an advocate; someone who can communicate and be assertive on your behalf. A student counsellor or other support worker should be able to help with that. I have various people that I can use to communicate things to others when I'm depressed or it's a subject that I'm somewhat blind to (like my own needs).
