I’ve always remembered the line “I’m not bad, I’m just drawn that way” as Jessica’s admission that while sexualized, she isn’t inherently a sexual entity.
I mean hell, literally, her line before is “You don’t know how hard it is being a woman looking the way I do.”, to which Eddie responds; “You don’t know how hard it is being a man looking at a woman looking the way you do.”
I think that’s pretty damning evidence to her asexuality. The whole plot point with Jessica is how everyone is either convinced she’s sleeping with every human and toon around, or why does she stay faithful to Roger.
Who Framed Roger Rabbit does a great job at satirizing Hollywood/American culture and ideals when it comes to appearances. It also does a great job at hiding some really well thought out challenges to how we look at others in plain sight.
I completely believe that Jessica Rabbit is an asexual romantic (hetero/bi/pan/etc not sure, and to be honest, I don’t know if that part is important, as she’s married to the toon she loves).
