>>52381636I guarantee these random neuron misfires happen between a slew of animals; We only really have the chance to record it when it happens to us, and human kindness is downright absurd compared to nature's brutality, so these things actually have a chance to be explored to begin with.
That's beside the point though.
There'd be a few Pokemon species who'd largely prefer humans, simply put. Depending on how smart you interpret Pokemon to be the reasons for such could be diverse: Could be drawn to obscured things like aura quality or spiritual presence, could be a simple physical preference like hair or eyes, or it could even stem from something like sapiosexuality or attraction to power.
Should you have sex with a Pokemon? If you can communicate, they're an adult, and they agree, I don't see why not, even if I think it's disgusting.
