Well they don't show them fucking. And that was the robot at that time, so if they were fucking then it was more like she was using a mechanical real doll than fucking.

Nosebleeds mean someones horny, yeah. My best guess for that one would be that they're turned on by Naota trying to save the city? I dunno. Its pretty fucked up. thats half the charm of it. :/
