Intersex is when you have sex organs that don't fit the "standard" definition of male or female. They are still sexual beings and can still feel arousal.
Asexual is when you don't have any sexual feelings or feelings of arousal, regardless of type of sexual organs.
So you can have someone who is asexual intersex, which would be an "intersex person with no feelings of arousal".
Also i'm pretty sure that asexuality is about attraction/desire for sex and st least some asexual people do experience arousal and have sex.
But, not being asexual, maybe i shouldn't comment.
