If your pokemons disappear, click on the bag or on cook and then go back, and they'll be there. Same happens after a sex scene, the fix is the same

I also got the bug where the same pokemon kept showing up, just restart the game 

The progression is a bit complicated, but i got it working, you find my reply a couple comments below

Agreeing that there's a lot of bugs.

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
