Make a list of which pokemon would you unironically have sex with one list for on model and one for off model , I'll start:
On model
Gardevoir (my wife do obviously)
Roserade
Tsareena
Lopunny
Florges (if possible)
Off model:
Same pokemon as what's in the on model list
Weavile
Meloetta
Lilligant
Froslass
Mismagius
Hatterene
Meowstic (female)
Mewtwo
Lurantis
Banette
There's probably more off model ones, but can't think of them off the top of my head.
