And somehow managed to be the first person in Starfleet history to get in trouble for it. Nobody else on that ship or on any ship ever got in trouble for boinking aliens.
Wasn't he held captive of that planet of women that wanted to snoo snoo him to death? And teleported long distance with an alien woman to see a sunrise? And had Seven basically throw herself on top of him?
They made it look death by snu snu but it wasn't. They harvested biological material by sucking the body dry.
Kim's such a nerd (affectionate) that the second he realized they actually teleported, and didn't step into a hologram, he basically lost all interest in her and started focusing on the technology instead.
He immediately balked at Seven too. Although I don't blame him there. She came off kinda strong.
Woa woa woa, how you gonna do my man like that? Also, he made captain. If he didn't let Janeway go to break the temporal prime directive there would be no more federation - just a whole lot of drones.
