>>45161270So pokemon that want to fuck their trainers? Really any Pokemon can fall into that line, it depends on the specific Pokemon in question though. Jame's Mareanie wanted to fuck/date/marry/romance him, but that doesn't mean every single Mareanie would want to do that to James or any Human for that matter. Its about preference.
If I could assume a Pokemon that MIGHT have some level of attraction for a Human Trainer, would either be Salazzle (It collects reverse harems, and its pheromones can apparently attract both human and Pokemon males) and Froslass (It collects handsome men to freeze and collect for their dens).
