Is it me, or is the progression towards intimacy with the pokemon harder? Any advice?
Aight got it working, keep petting them until they're tired, then let their energy recharge (you can notice it when there's a lot of hearts around them), and make them "show themselves" to you, after that make sure their energy is full, then you have to make out, remember to let their energy always fill up back to the fullest.
After that, sex is unlocked
