but she didn't want to bang him either.Harry was looking to explore a romantic relationship with Seven. He was attracted to her. That doesn't mean he wanted to bang her then and there in the mess hall. He's not an animal
Seven was trying to scare Harry off, and he was too dumb to figure that out, so he doesn't deserve to get any of that, if it had been on offer, which it wasn't.
Seven couldn't eat food at that point, so I doubt any of her sex/reproductive stuff was up to snuff, even for the most naive manchild on Voyager. Disconnected and nonpresent pipes, hells, I wouldn't be surprised if the Borg put a few hard drives where her uterus should have been lodged.
Besides, her cortical limiter would have killed Seven if she banged Harry.
