Have you ever spoken to this man directly? If not, I think you should. I think you should tell him (nicely but yet firmly) that his voyeurism bothers you. Tell him that you are not gay or bisexual and that he is creeping you out. Tell him he MUST stop or you shall have to take legal action. DO NOT get violent, ever. Unless you are physically defending yourself.
Have you ever stood close to this guy or any other guy there? I know that with AS, a lot of us tend to stand too close to people, talk too loud, too soft, etc. and this gives some people the wrong impression. You might try harder to watch your physical boundaries. Regardless, his behavior must stop and I think you are the only one capable of making it stop, short of pulling in the authorities.
